Question

Add:- -5x²y², -11/5x²y², 7x²y², 2/3x²y² please explain the method of doing it in as much as detail you can provide.​

Answer 1

Answer:

The answer is  2x²y²- 22/5x²y²

Step-by-step explanation:

   = -5x²y²-11/5x²y²+7x²y²+2/3x²y²

   = (-5x²y²+7x²y²) + (-11/5x²y²+2/3x²y²)-------> Taking L.C.M as 15

    = (2x²y²) + ((-33+10)/15x²y²)

     = 2x²y² + (-22/15x²y²)

      = 2x²y²- 22/5x²y²
