# Verify whether the following are zeros of the polynomial, indicated against them, or not p(x) = ax + b, x = -ba - Mathematics

Sum

Verify whether the following are zeros of the polynomial, indicated against them, or not

p(x) = ax + b, x = (-"b")/"a"

#### Solution

p(x) = ax + b, x = (-"b")/"a"

"p"((-"b")/"a") = "a"((-"b")/"a") + "b"

= −b + b

= 0

∴ (-"b")/"a" is the zero of the polynomial.

Is there an error in this question or solution?
