x^{2} - x - 6

$x^{2} - x - 6$

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

- 6

$- 6$ and whose sum is

- 1

$- 1$ .

- 3, 2

$- 3, 2$

Step 2

Write the factored form using these integers.

(x - 3) (x + 2)

$(x - 3) (x + 2)$
