Question

$$(-2)^{2}+5x(-2)+6$$

Evaluate

$10-10x$

Solution Steps

Calculate $-2$ to the power of $2$ and get $4$.

$$4+5x\left(-2\right)+6$$

Multiply $5$ and $-2$ to get $-10$.

$$4-10x+6$$

Add $4$ and $6$ to get $10$.

$$10-10x$$

Factor

$10\left(1-x\right)$

Solution Steps

Factor out $2$.

$$2\left(5-5x\right)$$

Consider $2-5x+3$. Multiply and combine like terms.

$$-5x+5$$

Consider $-5x+5$. Factor out $5$.

$$5\left(-x+1\right)$$

Rewrite the complete factored expression.

$$10\left(-x+1\right)$$
