How to solve x(x+2)+x(x-2)

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

Question

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

Evaluate

$2x^{2}$

Solution Steps

Use the distributive property to multiply $x$ by $x+2$.

$$x^{2}+2x+x\left(x-2\right)$$

Use the distributive property to multiply $x$ by $x-2$.

$$x^{2}+2x+x^{2}-2x$$

Combine $x^{2}$ and $x^{2}$ to get $2x^{2}$.

$$2x^{2}+2x-2x$$

Combine $2x$ and $-2x$ to get $0$.

$$2x^{2}$$
