Answer
21a - 9ab - 2b
Explanation
The question wants us to simplify the expression given
17a - 13ab + 4a - 2b + 4ab
The first step is to collect like terms and bring the terms with the same coefficient together
17a - 13ab + 4a - 2b + 4ab
= 17a + 4a - 13ab + 4ab - 2b
= 21a - 9ab - 2b
This cannot be simplified further. So, the simplified solution is
21a - 9ab - 2b
Hope this Helps!!!
