Question 106486: I need help I am adding and subtracting polynomials and I get it and I understand the steps on problem is I have come across a question that I dont 0understand okay this is the problem is
(12x^2y^2z^3+2+24x^2-(-2x^2y^2z^3+24x^2)okay so i did the first step i removed the parenthesis from the first part. Now im stuck i need to distrubute the minus sign threw out the parenthesis by changing the signs to there oppisites but i dont know if like for example where it says -2x^2 i know i change that to 2x^2 but then theres 2y^2 and i dont know if im suppsosed to change the sign of that or is that just one term and i leave it alone because my next step is to seperate and combine like terms anyways im confused if you could please help.

(12x^2y^2z^3+2+24x^2) - (-2x^2y^2z^3+24x^2)
= 12x^2y^2z^3+2x^2y^2z^3 + 2 + 24x^2-24x^2
= 14x^2y^2z^3 + 2
