SUMMARY

The derivative of the function (14x^2)/sqrt(1-x) is calculated using the quotient rule and chain rule of differentiation. The intermediate steps lead to the expression (28x(sqrt(1-x)) + (7x^2)/(sqrt(1-x)(1-x))) before simplifying to the final solution of (28x - 21x^2)/(1-x)^(3/2). This process highlights the importance of correctly applying differentiation rules to arrive at the correct derivative.

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?

for your equation above it should be 28x/sqrt(1-x) + 7x^2/(1-x)^3/2 then go from there..
