Step 1.1

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 $- 28$ and whose sum is $- 3$ .

$- 7, 4$

Step 1.2

Write the factored form using these integers.

$- 1 ((p - 7) (p + 4))$

Step 2

Remove unnecessary parentheses.

$- 1 (p - 7) (p + 4)$
