Question

what should be Subtracted from 5xy-7x²+3y² to get X²+y²+2²​

Answer 1

Answer:

We know that the equation is given

5xy -7x2+3y2 -x= x2 + y2 + 2×2

Answer 2

Answer:

5xy-8x^2+2y^2-4

Step-by-step explanation:

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

=5xy-7x^2+3y^2-(x^2+y^2+4)

=5xy-7x^2+3y^2-x^2-y^2-4

=5xy-7x^2-x^2+3y^2-y^2-4

=5xy-8x^2+2y^2-4
