Question

$$2 x ^ { 2 } - 4 x - 3 \quad ( 3 \quad 4 x + 3 - 2 x ^ { 2 }$$

Evaluate

$8x^{2}-106x-9$

Solution Steps

Use the distributive property to multiply $-3$ by $34x+3-2x^{2}$.

$$2x^{2}-4x-102x-9+6x^{2}$$

Combine $-4x$ and $-102x$ to get $-106x$.

$$2x^{2}-106x-9+6x^{2}$$

Combine $2x^{2}$ and $6x^{2}$ to get $8x^{2}$.

$$8x^{2}-106x-9$$

Expand

$8x^{2}-106x-9$

Solution Steps

Use the distributive property to multiply $-3$ by $34x+3-2x^{2}$.

$$2x^{2}-4x-102x-9+6x^{2}$$
