Understanding Linear Equations (ax + b = c)

A linear equation represents a straight-line relationship between variables. It has only one solution.

Formula Used:

x = (c - b) / a

Important Cases:

• If a = 0, the equation has no valid solution.
• If valid, the calculator directly returns the value of x.

Example:

Equation:
2x + 4 = 10

Solution:
x = (10 - 4) / 2
x = 3

So, the answer is x = 3

Understanding Quadratic Equations (ax² + bx + c = 0)

Quadratic equations involve squared variables and can have two, one, or no real solutions.

Formula Used:

Discriminant (D) = b² - 4ac

Solution Types:

1. Two Real Roots (D > 0)

If the discriminant is positive, the equation has two different solutions.

Formula:
x₁ = (-b + √D) / 2a
x₂ = (-b - √D) / 2a

2. One Real Root (D = 0)

If the discriminant equals zero, only one solution exists.

Formula:
x = -b / 2a

3. No Real Roots (D < 0)

If the discriminant is negative, the equation has no real solutions.

Example:

Equation:
x² - 5x + 6 = 0

Step 1: Identify values
a = 1, b = -5, c = 6

Step 2: Calculate discriminant
D = (-5)² - 4(1)(6)
D = 25 - 24 = 1

Step 3: Solve roots
x₁ = (5 + 1) / 2 = 3
x₂ = (5 - 1) / 2 = 2

Final Answer:
x₁ = 3, x₂ = 2
