Question

What are the x-intercepts of the quadratic functions f(x) = (x + 7)(x − 5)?

Answer 1

-7 and 5

Explanation:

To tell what the x intercepts are you set both (x+7) and (x-5) equal to zero and then subtract/ add it to zero and then you have the answer. So x+7=0 would be x=-7 and x-5=0 would be 5
