Question

(3a²-5ab+b²)+(-3a²+2b²+8ab

Answer 1

To solve this problem you must apply the proccedure shown below:
 1. You have the following expression given in the problem above: 
 (3a²-5ab+b²)+(-3a²+2b²+8ab)
 2. Therefore, you have:
 3a²-5ab+b²-3a²+2b²+8ab
 3ab+3b²
 3. To simplify the expression you can factor 3b, as following:
 3b(a+b)
 Therefore, the answer is: 3b(a+b)
