" 5."x^(2)+xy+y^(2)=100^(-1)

Find (dy)/(dx) , If x^(2)+ xy + y^(2)=100

Find (dy)/(dx) in the following x^(2) + xy + y^(2) = 100

Find (dy)/(dx) given x^(2) + xy + y^(2) = 100 .

Differentiate x^(2) + xy + y^(2) = 100 with respect to x.

If 5x^(2) -4xy +y^(2) -2x +1=0 then value of x+y is

Find (dy)/(dx) in the following: (a) x^(3)+x^(2)y+xy^(2)+y^(3)=81(b)xy+y^(2)=tan x+y(c)x^(2)+xy+y^(2)=100

Evaluate : 3x^(2) + 5xy - 4y^(2) + x^(2) - 8xy - 5y^(2)
