Question

$$(7x-xy+4 { y }^{ 2 } )-(6 { x }^{ 2 } -8xy-3 { y }^{ 2 } )$$

Evaluate

$7y^{2}+7x+7xy-6x^{2}$

Solution Steps

To find the opposite of $6x^{2}-8xy-3y^{2}$, find the opposite of each term.

$$7x-xy+4y^{2}-6x^{2}+8xy+3y^{2}$$

Combine $-xy$ and $8xy$ to get $7xy$.

$$7x+7xy+4y^{2}-6x^{2}+3y^{2}$$

Combine $4y^{2}$ and $3y^{2}$ to get $7y^{2}$.

$$7x+7xy+7y^{2}-6x^{2}$$

Expand

$7y^{2}+7x+7xy-6x^{2}$

Solution Steps

To find the opposite of $6x^{2}-8xy-3y^{2}$, find the opposite of each term.

$$7x-xy+4y^{2}-6x^{2}+8xy+3y^{2}$$

Combine $-xy$ and $8xy$ to get $7xy$.

$$7x+7xy+4y^{2}-6x^{2}+3y^{2}$$

Combine $4y^{2}$ and $3y^{2}$ to get $7y^{2}$.

$$7x+7xy+7y^{2}-6x^{2}$$
