x = 7 and x = -8

Answer 1

The zeros of this quadratic function are (D) x=7 and x=-8.

What is Quadratic Function?

Quadratic function is a relation or expression in which highest power of the variable is 2.

Given the quadratic function is $f(x)=(x-7)(x+8)$

So the zeros are found by solving $f(x)=0$.

On solving $f(x)=0$ we get,

$(x-7)(x+8)=0$

We know that if the product of two mathematical expression is zero then at least one of them is zero.

Either, $x-7=0\Rightarrow x=7$

Or, $x+8=0\Rightarrow x=-8$

Hence the zeros for the given quadratic function $f(x)=(x-7)(x+8)$ are $x=7$ and $x=-8$.
