Answer:
(x-8)(x+7) in which x = 8, -7 (if needed)
Step-by-step explanation:
Figure out first what two numbers can go to 56. The possible combinations are 1 and 56, 2 and 28, 4 and 14, and 7 and 8. The middle number has to equal the sum of -1. Therefore, 7 and 8 will go to that sum with -8 as one and +7 as another. Your factor should be (x - 8) (x + 7) and when you are finding for the x-values, it should be 8 and -7 when necessary.
