If you mean zeros, then to find the root of a function you just find the zeros.

Which equation is not a quadratic equation?

BabaBlast [244]

A quadratic equation is usually in the form:

$ax^{2} +bx +c$

where a, b and c are the coefficients of the expression and a ≠ 0.

If a = 0, the equation becomes a linear expression and is no longer quadratic.

Hence, in the above options; y = 5x -2 is the only one that is not a quadratic equation.
