Question

Why cant the a value in the standard form of a quadratic function ax^2+bx+c=0 be equal to 0?

Answer 1

the equation is no longer quadratic

Explanation:

A quadratic equation is a polynomial equation in which the highest-degree term has degree 2.

What happens when a = 0?

The value a=0 makes the squared term disappear. If 'a' is zero, the equation becomes a linear equation, not a quadratic equation:

bx +c = 0
