Discover some interesting facts about Academic
First-degree equation and how to solve it.
A first-degree equation is a polynomial equation in which the highest exponent of the variable is 1.
General form:
It is written as:
\( ax + b = 0 \)
Where:
a and b → are known numbers (constants).
x → is the unknown variable.
What is the solution?
The solution is the value of x that makes the equation true.
How to solve (step by step):
1️⃣ Isolate the term with x:
Put the term with x alone on one side.
Move the other terms to the other side.
2️⃣ Simplify the equation:
Perform operations on both sides.
Add or subtract values.
3️⃣ Isolate the variable:
Divide both sides by the coefficient of x.
Leave x alone.
4️⃣ Find the solution:
The value obtained for x is the solution of the equation.
It makes the equality true.
Example of General Form:
Equation: \( ax + b = 0 \)
Goal: find x.
Simple summary:
First-degree equation: \( ax + b = 0 \)
Steps:
isolate x.
simplify.
divide.
solve.
Special case:
Usually there is one unique solution.
If any value of x works, it is an identity.
Quadratic equations and their solutions
A quadratic equation (or second-degree equation) is a polynomial equation in which the highest exponent of the variable is 2.
General form:
It is written as:
\( ax^2 + bx + c = 0 \)
Where:
a, b, c → are constant numbers (with \( a \neq 0 \)).
x → is the unknown variable.
How to find the solutions?
First, we calculate the discriminant (Δ):
\( \Delta = b^2 - 4ac \)
It determines how many solutions the equation has.
Types of solutions:
1. Two real and different roots:
When: \( \Delta > 0 \)
✔️ The equation has two distinct real solutions.
✔️ The x values are different.
2. Two equal real roots:
When: \( \Delta = 0 \)
✔️ The equation has one repeated solution.
✔️ Both roots are equal.
3. No real roots:
When: \( \Delta < 0 \)
❌ There are no real solutions.
✔️ The solutions are complex numbers.
Simple summary:
Second-degree equation: \( ax^2 + bx + c = 0 \).
Discriminant: \( \Delta = b^2 - 4ac \).
Types of solutions:
\( \Delta > 0 \) → 2 different roots.
\( \Delta = 0 \) → 1 double root.
\( \Delta < 0 \) → no real roots.
Molar Mass
Molar mass is a physical property that indicates the mass of a substance at the molecular level.
Basic definition:
It represents the mass of 1 mole of a substance.
It is calculated by adding the atomic masses of all atoms in a chemical formula.
Unit of measurement:
👉 g/mol (grams per mole).
This means:
how many grams are present in 1 mole of a substance.
Simple example:
If a substance has a molar mass of:
👉 32 g/mol.
✔️ It means:
1 mole of that substance = 32 grams.
How to calculate molar mass:
1️⃣ Identify the chemical formula:
Check how many atoms of each element are present.
2️⃣ Consult the periodic table:
Find the atomic mass of each element.
Each element has an average value in g/mol.
3️⃣ Multiply and add:
Multiply the atomic mass by the number of atoms.
Add all the results.
What is atomic mass?
It is the value found in the periodic table.
It represents the average mass of an element’s isotopes.
It is used as the basis for calculating molar mass.
Simple summary:
Molar mass = mass of 1 mole of a substance.
Unit: g/mol.
Calculated by adding the atomic masses of the elements.
The periodic table is used as reference.
The Rise of Greek Civilization
Ancient Greece was one of the most important civilizations in history and developed in a strategic region of the Mediterranean Sea.
Geographical location:
Greece is located on the Balkan Peninsula.
It is surrounded by the Mediterranean Sea.
It has many islands, mainly in the Aegean Sea.
👉 This location favored trade and navigation.
Origin of Greek civilization:
Greek civilization emerged around the 8th century BC.
It originated in three main areas:
Mainland Greece.
Islands of the Aegean Sea.
Coasts of Asia Minor.
Expansion of Ancient Greece:
Over time, the Greeks spread throughout the Mediterranean.
They created colonies in several regions, which helped to:
expand trade.
strengthen the economy.
spread Greek culture.
Importance of colonies:
Colonies were not just territories:
they maintained ties with mainland Greece.
they exchanged goods and ideas.
they helped spread Greek culture and language.
The Origin of the Conditions for Life
The emergence of life did not happen all at once. Over millions of years, several events transformed the Earth and created the necessary conditions for the first living beings.
Formation of planet Earth:
Earth formed after collisions with bodies from the Solar System.
These impacts helped shape the primitive planet.
At first, the environment was extremely hot and unstable.
Formation of the crust, continents, and oceans:
As the planet cooled:
a solid crust formed.
continents began to develop.
oceans came into existence.
This created environments where life could develop.
Formation of the atmosphere:
Earth developed an atmosphere:
rich in gases.
capable of producing a natural greenhouse effect.
This helped maintain temperatures suitable for liquid water to exist.
Tectonic plates and volcanic activity:
The planet continued changing through:
movement of tectonic plates.
intense volcanic activity.
These processes changed the landscape and released important substances into the environment.
Atmospheric electrical phenomena:
Storms and electrical discharges:
helped trigger primitive chemical reactions.
favored the formation of important molecules.
Formation of the first molecules:
Over time, there appeared:
simple organic molecules.
more complex macromolecules.
These substances were essential for the emergence of life.
First primitive cells:
With time:
simple life forms appeared.
the first primitive cells emerged.
This was one of the most important steps in Earth’s history.
Photosynthesis and oxygen:
Some organisms began to perform photosynthesis:
they produced oxygen.
they transformed Earth’s atmosphere.
This allowed more complex forms of life to develop.
Formation of the ozone layer:
With more oxygen:
the ozone layer formed.
it began protecting Earth from intense solar radiation.
Super ice ages and new environments:
Major ice ages:
changed the planet.
created new environments and ecosystems.
This encouraged new adaptations among living beings.
