SOLUTION: Problem: (x-1)(x-1)(x-1)=y. solve for x I worked the problem by multiplying and got: x^3-3x^2+3x-1=y then went to x^3-3x^2+3x = y +1 I honestly dont know what to do from her

Question 308125: Problem: (x-1)(x-1)(x-1)=y. solve for x
I worked the problem by multiplying and got:
x^3-3x^2+3x-1=y
then went to x^3-3x^2+3x = y +1
I honestly dont know what to do from here.
thanks sheri

You can put this solution on YOUR website!
(x - 1)^3 = y

x - 1 = cuberoot(y)

x = [cuberoot(y)] + 1 = [y^(1/3)] + 1
