[ Step One ] Remove Parenthesis (a) = a
[tex]\bold{x^4+x^3+x^2+x-\left(x^4-x^3+x^2-x\right)}[/tex]
[ Step Two ] Rewrite [tex]\bold{-\left(x^4-x^3+x^2-x\right)}[/tex]
[tex]\bold{-x^4+x^3-x^2+x}[/tex]
[ Step Three ] Rewrite Equation
[tex]\bold{x^4+x^3+x^2+x-x^4+x^3-x^2+x}[/tex]
[ Step Four ] Simplify [tex]\bold{x^4+x^3+x^2+x-x^4+x^3-x^2+x}[/tex]
[tex]\bold{2x^3+2x}[/tex]
[ Step Five ] Simplify
[tex]\bold{2x^3+2x}[/tex]
