Answer 2

Answer:

3x²+xy-y²-(x²-xy+2y²)

Because there is a negative(-) sign before a bracket, the sign of all the numbers in the bracket will change, i.e. positive sign(+) will change to negative(-) and vice versa.

3x²+xy-y²-x²+xy-2y²

Now, we will regroup all the like terms.

(3x²-x²)+(xy+xy)-y²-2y²

2x²+2xy-3y² Ans
