Question

Пожалуйста, очень нужно!!!
4m^4 + 4m^2 - 13 + 4m^4 - 4m^2 +13
(4m^4 + 4m^2 - 13) - (4m^4 - 4m^2 +13)

Answer 1

4m^4 + 4m^2 - 13 + 4m^4 - 4m^2 +13=8m^4
(4m^4 + 4m^2 - 13) - (4m^4 - 4m^2 +13)=4m^4+4m^2-13-4m^4+4m^2-13=8m^2-26

Answer 2

4m^4 + 4m^2 - 13 + 4m^4 - 4m^2 +13=4m^4 +4m^4=8m^4
(4m^4 + 4m^2 - 13) - (4m^4 - 4m^2 +13)=4m^4 + 4m^2 - 13 - 4m^4 + 4m^2 -13=
=8m^2-26
