1. y^2 = e^(x^2) + 2x

I already got the 1st one which is: (xe^(x^2) + 1) / y

for the 2nd:

((y)(e^(x^2) + (2x^2)e^(x^2)) - (xe^(x^2) + 1)(y')) / y^2

((y)(e^(x^2) + (2x^2)e^(x^2)) - (xe^(x^2) + 1)((xe^(x^2) + 1) / y))

/ y^2

Multiplied by y and got:

(y^2*e^(x^2) ( 1+2x^2) - (xe^(x^2) + 1)(xe^(x^2) + 1)) / y^3 and this

is where I totally got lost... but the book said the answer is

(((2x^2)*(y^2) + y^2 - 2x)(e^(x^2)) - x^2e^(2x^2) - 1) / y^3
