Factor x^2+(-7x)+(-8)

$x^{2} + (- 7 x) + (- 8)$

Step 1

Remove parentheses.

$x^{2} - 7 x - 8$

Step 2

Factor $x^{2} - 7 x - 8$ using the AC method.

Consider the form $x^{2} + b x + c$ . Find a pair of integers whose product is $c$ and whose sum is $b$ . In this case, whose product is $- 8$ and whose sum is $- 7$ .

$- 8, 1$

Write the factored form using these integers.

$(x - 8) (x + 1)$
