Question

$$9x^{2}-16+(x+2)(3x-4)$$

Evaluate

$2\left(6x^{2}+x-12\right)$

Solution Steps

Use the distributive property to multiply $x+2$ by $3x-4$ and combine like terms.

$$9x^{2}-16+3x^{2}+2x-8$$

Combine $9x^{2}$ and $3x^{2}$ to get $12x^{2}$.

$$12x^{2}-16+2x-8$$

Subtract $8$ from $-16$ to get $-24$.

$$12x^{2}-24+2x$$

Expand

$12x^{2}+2x-24$

Solution Steps

Use the distributive property to multiply $x+2$ by $3x-4$ and combine like terms.

$$9x^{2}-16+3x^{2}+2x-8$$

Combine $9x^{2}$ and $3x^{2}$ to get $12x^{2}$.

$$12x^{2}-16+2x-8$$

Subtract $8$ from $-16$ to get $-24$.

$$12x^{2}-24+2x$$
