Welcome to Quadratic Equations!

Learn to identify, understand, and work with
quadratic equations step by step

What is a Quadratic Equation?

A quadratic equation has the standard form:

ax² + bx + c = 0
where a ≠ 0

The key requirement is that the coefficient of x² cannot be zero,
otherwise it would not be a quadratic equation!

Real Examples

2x² + x - 300 = 0
Prayer hall expansion problem
x² - 45x + 324 = 0
Marbles arrangement problem
x² - 55x + 750 = 0
Toys production optimization

Notice how each follows the pattern ax² + bx + c = 0

How to Identify Quadratic Equations

Step 1
Simplify the equation first
Combine like terms and move everything to one side
Step 2
Check the form ax² + bx + c = 0
Look for the highest power of x to be 2
Step 3
Verify a ≠ 0
The coefficient of x² must not be zero

Key Point: Sometimes equations look quadratic but aren't, and vice versa!

Step-by-Step Example

Let's analyze: 3x² - 2x² + 5x - 1 = 2x + 3
