x^{2} + x - 2

$x^{2} + x - 2$

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

- 2

$- 2$ and whose sum is

1

$1$ .

- 1, 2

$- 1, 2$

Step 2

Write the factored form using these integers.

(x - 1) (x + 2)

$(x - 1) (x + 2)$
