Question

What are the zeroes of f(x)=(x-7)(x+8)

Answer 1

The zeroes of f(x) = (x-7)(x+8) are 7 and -8.

Explanation:

You have to figure out what makes each of the equal to zero.

Step 1 : Make the 2 equations both equal 0.

x-7 = 0

x+8 = 0

Step 2: Solve for x

x-7 = 0

x=7

x+8 = 0

x=-8

So 7 and -8 are both zeroes of this function.
