What process could you use to solve equations of the form (x + a)(x + b) = 0? In this case there are only two factors (values being multiplied) that are being set equal to 0. How would you solve the equation if there were more than two factors? Explain.

What you have here is

(x + a) * (x + b) = 0

The ONLY way that two things can multiply together to give zero is if ONE or BOTH of them IS ZERO.

so

x+a=0 or x+b=0

Now you can 'digest' that properly and then finish the question.
