Question

Simplify completely

Answer 1

Answer: D

Step-by-step explanation:

$\frac{x^{2}-15x+56} {x-7}$

First, factor the numerator (top):

x² - 15x + 56

                ∧

              -1   -56

              -2  -28

              -4   -14

              -7    -8  = -15

        (x - 7)(x - 8)

Next, cancel out like terms from the numerator and denominator:

$\frac{(x-7)(x-8)} {x-7}$ = x - 8
