[SOLVED] Algebta (factoring polynomials)
x^2 * [ (1/2) * (1-x^2)^(-1/2) * (-2x)] + (1 - x^2)^(1/2) * (2x)
factor this down.
n/a
-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.
Homework Statement
x^2 * [ (1/2) * (1-x^2)^(-1/2) * (-2x)] + (1 - x^2)^(1/2) * (2x)
