so i guess we learned this when i was sick at schoolits due tomorrow and if i dont finish this ill drop from a b to a D. so i reallly need help.so it says; Find the additive inverse of each polynomial.and the examples are: Sample 1: 6y-3z Solution: -6y+3zSample 2: -a?-2ab+3b?Solution: a?-2ab+3b?i DONT UNDERSTAND THIShow do they get the answer?could you do this problem for me and explain how you did it? : 2a+9b 4xy?+6x?y-y?PLEASEthis depends on my grade for this semester.
The first example makes sense. You add the two and you get 0. Do you have the signs right in the second solution? 2a+9b -2a-9b Add them and you get 0 4xy^2+6x^2y-y^3 -4xy^2-6x^2y+y^3 It's a matter of changing the signs and adding. The additive inverse is what's added that will give 0, the identity for addition.
