Factor 2x^2-4x-4

$2 x^{2} - 4 x - 4$

Step 1

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

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

Step 2

Factor $2$ out of $- 4 x$ .

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

Step 3

Factor $2$ out of $- 4$ .

$2 x^{2} + 2 (- 2 x) + 2 \cdot - 2$

Step 4

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

$2 (x^{2} - 2 x) + 2 \cdot - 2$

Step 5

Factor $2$ out of $2 (x^{2} - 2 x) + 2 \cdot - 2$ .

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