Factor 2x^3-6x^2-20x

$2 x^{3} - 6 x^{2} - 20 x$

Step 1

Factor $2 x$ out of $2 x^{3} - 6 x^{2} - 20 x$ .

Factor $2 x$ out of $2 x^{3}$ .

$2 x (x^{2}) - 6 x^{2} - 20 x$

Factor $2 x$ out of $- 6 x^{2}$ .

$2 x (x^{2}) + 2 x (- 3 x) - 20 x$

Factor $2 x$ out of $- 20 x$ .

$2 x (x^{2}) + 2 x (- 3 x) + 2 x (- 10)$

Factor $2 x$ out of $2 x (x^{2}) + 2 x (- 3 x)$ .

$2 x (x^{2} - 3 x) + 2 x (- 10)$

Factor $2 x$ out of $2 x (x^{2} - 3 x) + 2 x (- 10)$ .

$2 x (x^{2} - 3 x - 10)$

Step 2

Factor.

Factor $x^{2} - 3 x - 10$ 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 $- 10$ and whose sum is $- 3$ .

$- 5, 2$

Write the factored form using these integers.

$2 x ((x - 5) (x + 2))$

Remove unnecessary parentheses.

$2 x (x - 5) (x + 2)$
