# y =1 - 3/(4x^3 -1)#

#y' = 4x^2 (y-1)^2, y(0) =1#

This is separable:

#1/(y-1)^2 y' = 4x^2 #

#int 1/(y-1)^2 y' dx =int 4x^2 dx#

#int 1/(y-1)^2 dy =int 4x^2 dx#

# -1/(y-1) = (4x^3)/3 + C#

# -(y-1) = 1/((4x^3)/3 + C) = 3/(4x^3 + C)#

# y =1 - 3/(4x^3 + C)#

# y(1) = 0 = 1 - 3/(4 + C)#

#4 + C = 3, C = -1#

# y =1 - 3/(4x^3 -1)#
