Question

what is quadratic equation write an example​

Answer 1

$\huge{ Answer }$

 A quadratic equation is any equation having the form where x represents an unknown, and a, b, and c represent known numbers, with a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term.

Formula : ax² + bx + c = 0

( a,b,c known numbers, where a ≠ 0)

( x = unknown )


Examples of quadratic equations include all of these:

1) y = x² + 3x + 1.

2) y = x²

3) y = 2x² + 4x - 9

4) y = x² - 9

5) A = pi × r²
