Homework Statement
derivative of: (14x^2)/sqrt(1-x)
Homework Equations
The Attempt at a Solution
I am at this point at finding the derivative:
(28x(sqrt(1-x))+((7x^2)/sqrt(1-x))/(1-x)
I am confused about the next step because don't know how it's derived from the previous attempt:
Final solution: (28x-21x^2)/(1-x)^3/2
How is this derived?
