Answer:

Given to find sum of  2x^2+3xy-5  and  7+2xy-x^2

(2x^2+3xy-5)+(7+2xy-x^2)= (2x^2-x^2)+(3xy+2xy)+(-5+7)

                                                   =x^2+5xy+2

Now we should find the difference between  x^2+5xy+2  and  3xy + x^2 -2

(x^2+5xy+2)-(3xy+x^2-2)= (x^2-x^2)+(5xy-3xy)+[2-(-2)]

                                                  = 0 +2xy+ (2+2)

                                                  =2xy+4

                    Hope it helps you^_^
