Perform each of the operations below and put your answers in descending order with regard to the x variable? I don't understand the question. Solve then put the answers in descending order?
You need to expand the brackets and then group like terms.
$\displaystyle (12x^2y^2z^3+2+24x^2)-(-2x^2y^2z^3+24x^3+24x^2)$
$\displaystyle 12x^2y^2z^3+2+24x^2+2x^2y^2z^3-24x^3-24x^2$
$\displaystyle 14x^2y^2z^3+2-24x^3$
In decending order of x
$\displaystyle -24x^3+14x^2y^2z^3+2$
