What Are Quadratic Equations?
Think of a quadratic equation as a special type of math problem that always has an x² term. Unlike the linear equations you're used to, these have a curved relationship instead of a straight line.
Every quadratic equation follows the standard form: ax² + bx + c = 0, where a, b, and c are regular numbers, but a can never be zero (otherwise it wouldn't be quadratic anymore!). The quadratic term is the ax² part, the linear term is bx, and c is called the constant term.
💡 Remember: If there's no x² term, it's not a quadratic equation!
For example, in 2x² + 5x - 3 = 0, you have a = 2, b = 5, and c = -3. Sometimes you'll need to rearrange equations to get them in standard form first.
