Question

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

Answer 1

Answer:

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

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

Step-by-step 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:

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