Question

Simplify x-x^3/x-1

Answer 1

\[x-x ^{3}=x(1-x ^{2})=x(1-x)(1+x)=-x(1-x)(x-1)\]
\[x-x ^{3}/(x-1)=-x(x+1)\]

Answer 2

how is this happen? −x(1−x)(x−1)

Answer 3

correction
x−x3=x(1−x2)=x(1−x)(1+x)=−x(x-1)(x+1)
x−x3/(x−1)=−x(x+1)

Answer 4

-(1-x)=(x-1)

Answer 5

oh... okay what if, the answer is this x(x+1) is it okay?

Answer 6

No, he answer is :
f(x)=-x(x+1)
