Answer 1

Answer:

(x - 7)(x - 8)

Step-by-step explanation:

Factor this into the form:

(x +/- a)(x +/- b)

As the third term is a positive and the second is negative, we know that the two operators are subtract:

(x - a)(x - b)

Find the factors of 56:

1 56

2 28

4 14

7 8

The two factors we need will add up to 15, so this is 7 and 8. This means the factor form is:

(x - 7)(x - 8)
