Question

$$(4 { x }^{ 2 } -1)-(6 { x }^{ 2 } +x+1)$$

Evaluate

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

Solution Steps

To find the opposite of $6x^{2}+x+1$, find the opposite of each term.

$$4x^{2}-1-6x^{2}-x-1$$

Combine $4x^{2}$ and $-6x^{2}$ to get $-2x^{2}$.

$$-2x^{2}-1-x-1$$

Subtract $1$ from $-1$ to get $-2$.

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

Expand

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

Solution Steps

To find the opposite of $6x^{2}+x+1$, find the opposite of each term.

$$4x^{2}-1-6x^{2}-x-1$$

Combine $4x^{2}$ and $-6x^{2}$ to get $-2x^{2}$.

$$-2x^{2}-1-x-1$$

Subtract $1$ from $-1$ to get $-2$.

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