Solve by Factoring 5x^2+10x=0

$5 x^{2} + 10 x = 0$

Step 1

Factor $5 x$ out of $5 x^{2} + 10 x$ .

Factor $5 x$ out of $5 x^{2}$ .

$5 x (x) + 10 x = 0$

Factor $5 x$ out of $10 x$ .

$5 x (x) + 5 x (2) = 0$

Factor $5 x$ out of $5 x (x) + 5 x (2)$ .

$5 x (x + 2) = 0$

Step 2

If any individual factor on the left side of the equation is equal to $0$ , the entire expression will be equal to $0$ .

$x = 0$

$x + 2 = 0$

Step 3

Set $x$ equal to $0$ .

$x = 0$

Step 4

Set $x + 2$ equal to $0$ and solve for $x$ .

Set $x + 2$ equal to $0$ .

$x + 2 = 0$

Subtract $2$ from both sides of the equation.

$x = - 2$

Step 5

The final solution is all the values that make $5 x (x + 2) = 0$ true.

$x = 0, - 2$
