Find an expression which represents the sum of (-3x-4y)(−3x−4y) and (x+3y)(x+3y) in simplest terms
ella [17]

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
