x^{2} + 2 x - 8

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

Step 1

Consider the form

x^{2} + b x + c

$x^{2} + b x + c$ . Find a pair of integers whose product is

c

$c$ and whose sum is

b

$b$ . In this case, whose product is

- 8

$- 8$ and whose sum is

2

$2$ .

- 2, 4

$- 2, 4$

Step 2

Write the factored form using these integers.

(x - 2) (x + 4)

$(x - 2) (x + 4)$
