Question

Find an expression which represents the sum of (-3x-4y)(−3x−4y) and (x+3y)(x+3y) in simplest terms

Answer 1

The sum of (−3x−4y) and (x+3y) in simplest terms will be:

`\left(-3x-4y\right)+\left(x+3y\right)=-2x-y`

Explanation:

Given

• (−3x−4y)

• (x+3y)

Finding the sum of (−3x−4y) and (x+3y)

`\left(-3x-4y\right)+\left(x+3y\right)`

`=-3x-4y+x+3y`

`=-3x+x-4y+3y`

`=-2x-4y+3y`

`=-2x-y`

Therefore, the sum of (−3x−4y) and (x+3y) in simplest terms will be:

`\left(-3x-4y\right)+\left(x+3y\right)=-2x-y`
