Question

Find the smallest zero for the function. h(x)=4x•4x-8x-60

Answer 1

-3

Explanation:

First multiply.

4x * 4x = 4x^2

Then write it out.

4x^2 - 8x - 60 = 0

Then we can take out 4 out of everything.

4(x^2 - 2x - 15) = 0

Then we can factor.

4(x - 5)(x + 3) = 0

So the zeros of the function are 5 and -3.

The smallest of those two is -3.
