Question

Factor x^3+x^2+2x+5-2x^3-x^2-x-5=0

Answer 1

x^3+x^2+2x+5-2x^3-x^2-x-5=0 The 5's cancel, the x^2's cancel, combine like terms and thus far you have:
x-x^3=0
Factor out an "x" for the final answer of:
\[x(1-x^2)=0\]

Answer 2

You can go one step further...\[x(1+x)(1-x)=0\]Now that all this has been done, why not write down the solutions of this equation?
