Answer 1

Answer:

The zeros of the function are x=-7 and x=2

Step-by-step explanation:

we have

$A(x)=(x-2)(x+7)$

we know that

The zeros or roots of the function are the values of x when the value of the function is equal to zero (also is called the x-intercepts)

so

For A(x)=0

$(x-2)(x+7)=0$

Remember that

The Zero Product Property states that

if ab = 0, then either a = 0 or b = 0, or both a and b are 0

so

Let

$(x-2)=0$ ----> $x=2$

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

therefore

The zeros of the function are x=-7 and x=2
