subtract as indicated.

1.) -12x - 14x =

2.) -24m - (-11m) =

3.) 16ab^2 - 17ab^2 =

4.) (a - 1) - (a - 8) =

1. -36x
2.-13m
3.-1ab^2 or -ab^2(Since you need not to specifically put 1 for ab^2 will have a constant of 1)
4.Let's use distributive property (a-1)(-a-8) = -a^2+1a-8a+9 = a^2-7a+9 <~ this is the final answer.
1)  - 36x

2)  -24 + (+ 11m)  = -13m

3)  -ab²

4)  (a-1) + (-a + 8) = 7
