If `x^(2)+(x)/(y^(2))=y^(2)+(y)/(x^(2))=2` then find `x^(2)+y^(2)`

If y=|x-x^(2)|, then find (d^(2)y)/(dx^(2))

Simplify: x^(2)(x-y)y^(2)(x+2y)

If a=(x)/(x^(2)+y^(2)) and b=(y)/(x^(2)+y^(2)) then value of (x+y) is

If x^(2) + y^(2) = 12 xy , then find the value of (x^(2))/(y^(2)) + (y^(2))/(x^(2)) .

(x+y)^(3)-(x-y)^(3) can be factorized as 2y(3x^(2)+y^(2)) (b) 2x(3x^(2)+y^(2))2y(3y^(2)+x^(2)) (d) 2x(x^(2)+3y^(2))

If (3x-y):x(4x+y)=5:12 then find (x^(2)+y^(2)):(x+y^(2))

a=(x)/(x^(2)+y^(2)) and b=(y)/(x^(2)+y^(2)) then find the value of x+y

a=(x)/(x^(2)+y^(2)) and b=(y)/(x^(2)+y^(2)) then find the value of x+y

a=(x)/(x^(2)+y^(2)) and b=(y)/(x^(2)+y^(2)) then find the value of x+y
