Factor 2y^2-2y-4

$2 y^{2} - 2 y - 4$

Step 1

Factor $2$ out of $2 y^{2} - 2 y - 4$ .

Factor $2$ out of $2 y^{2}$ .

$2 (y^{2}) - 2 y - 4$

Factor $2$ out of $- 2 y$ .

$2 (y^{2}) + 2 (- y) - 4$

Factor $2$ out of $- 4$ .

$2 (y^{2}) + 2 (- y) + 2 (- 2)$

Factor $2$ out of $2 (y^{2}) + 2 (- y)$ .

$2 (y^{2} - y) + 2 (- 2)$

Factor $2$ out of $2 (y^{2} - y) + 2 (- 2)$ .

$2 (y^{2} - y - 2)$

Step 2

Factor.

Factor $y^{2} - y - 2$ 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 $- 2$ and whose sum is $- 1$ .

$- 2, 1$

Write the factored form using these integers.

$2 ((y - 2) (y + 1))$

Remove unnecessary parentheses.

$2 (y - 2) (y + 1)$
