a + (b + c) - (d - e)Combine like terms:= a + b + c - d + e a (2a + 4a) - b (3b - 4b)Simplify inside the parentheses:= a (6a) - b (-b)= 6a^2 + b^2 h (t (2 + 8) + b - (5b / b) (2z - 1))Simplify inside the parentheses:= h (t (10) + b - 5 (2z - 1))= h (10t + b - 10z + 5)= 10ht + hb - 10hz + 5h (8b - 2a) (2 - 5)Distribute:= (8b - 2a) (-3)= -24b + 6a 2dt (a - 2b) - 6a - 3b / 6 (11c - 5f) + 6 (3f - 4c)Distribute and simplify:= 2dta - 4dtb - 6a - (1/2)b (11c - 5f) + 18f - 24c= 2dta - 4dtb - 6a - (11/2)bc + (5/2)bf + 18f - 24c
