Answer 1

Here are all your solutions:-

1. A+B=(2y²+3x-x²)+(3x²-y²)

A+B=y²+2x²+3x

2.A-B=2y²+3x-x²-(3x²-y²)

  A-B=2y²+3x-x²-3x²+y²

 A-B=3y²-4x²+3x

3.B+C=3x²-y²+5x²-3xy

B+C=8x²-y²-3xy

4.B-C=3x²-y²-(5x²-3xy)

B-C=3x²-y-5x²+3xy

B-C=8x²-y²+3xy

5.A+B+C=y²+2x²+3x+5x²-3xy

A+B+C=y²+7x²+3x-3xy

6.A+B-C=y²+2x²+3x-(5x²-3xy)

A+B-C=y²+2x²+3x-5x²+3xy

A+B-C=y²+-3x²+3x+3y

Hope it helps!!
