What is a solution to (x + 6)(x + 2) = 60?
x = −6
x = −4
x = 4
x = 12

x=4

Step-by-step explanation:

You could factor to find all solutions like such:

Or you could just plug in each multiple choice as x and see which one equals 60.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
