Answer:
x = 7, x = -2
Step-by-step explanation:
(x-7) (x+2) = 0
Zero product property: In order to get a product (the answer to a multiplication problem) of 0, you need to have at least one of the numbers being multiplied be 0. For example, in x * y = 0, either x or y needs to be equal to 0.
Using this, we know that either (x - 7) or (x + 2) is 0. So,
x - 7 = 0
Add 7 to both sides.
x = 7
x + 2 = 0
Subtract 2 from both sides.
x = - 2
So, the answer is x = 7 or x = -2
