the sum of two expressions is `x^2-y^2-2xy+y-7` If one of them is `2x^2+3y^2-7y+1` then the other is

LCM of two expressions is 12x^(2)y^(2)z and their HCF is 4xy , if one of them is 4x^(2)y , then the second expression, is

The least value of expression x^(2)+2xy+2y^(2)+4y+7 is

One of the factors of the expression (2x-3y)^(2)-7(2x-3y)-30 is

How much is -x^(2)+7y^(2)-3xy less than 2x^(2)-y^(2)+xy ?

The product of the rational expressions (x^2 - y^2)/(x^2 + 2xy + y^2) and (xy + y^2)/(x^2 - xy) is:

Find the sum of the following algebraic expressions : 2x^(2) + 4y^(2) + 7 , - 3y^(2) + 8 , -x^(2) -2y^(2) - 2

If x^2+y^2=7 and xy=2 then x^4-2x^2y^2+y^4=
