Find dy/dx by implicit differentiation: x^4 (x+y) = y^2 (3x-y)
I got [ 3y^2 - 4x^4 - 4x^3 y ] / [ 3y^2 + 4x - 6xy ] but the textbook answer is the same except the denominator term 4x^4 is 5x^4 instead ...?
show steps ... maybe we can point out where you went wrong
oh pellet i know actually nvm
x^4 (x+y) ... this is were you get 5x^4
