Question

$$(x-x)^{2}+3(x^{2}-x)-90$$

Evaluate

$3\left(x-6\right)\left(x+5\right)$

Solution Steps

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

$$0^{2}+3\left(x^{2}-x\right)-90$$

Calculate $0$ to the power of $2$ and get $0$.

$$0+3\left(x^{2}-x\right)-90$$

Use the distributive property to multiply $3$ by $x^{2}-x$.

$$0+3x^{2}-3x-90$$

Subtract $90$ from $0$ to get $-90$.

$$-90+3x^{2}-3x$$

Expand

$3x^{2}-3x-90$

Solution Steps

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

$$0^{2}+3\left(x^{2}-x\right)-90$$

Calculate $0$ to the power of $2$ and get $0$.

$$0+3\left(x^{2}-x\right)-90$$

Use the distributive property to multiply $3$ by $x^{2}-x$.

$$0+3x^{2}-3x-90$$

Subtract $90$ from $0$ to get $-90$.

$$-90+3x^{2}-3x$$
