You can put this solution on YOUR website!
(6x – 2x – x2) – (-10 + 4x – x2)
Open the brackets
6x-2x-x^2 +10-4x+x^2 ( When there is a negative sign before the bracket the signs become opposite when you open the bracket)
Group all the common terms and add up all the common terms
6x-2x-4x-x^2+x^2+10
Ans = 10
