**[SOLVED] Algebta (factoring polynomials)**

## Homework Statement

x^2 * [ (1/2) * (1-x^2)^(-1/2) * (-2x)] + (1 - x^2)^(1/2) * (2x)

factor this down.

## Homework Equations

n/a

## The Attempt at a Solution

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

I understand how you get to this part, but I can't get to:

x * (2 - 3x^2)/ (sqrt(1 - x^2))

after trying factoring by substitution etc.
