Answer:
Below
Step-by-step explanation:
First we combine your first set of terms,
7b^2 + 2b^2 = 9b^2
There's a subtraction hidden in there!
9b^2 - 3b^2 = 6b^2
Next we do the same thing for the second term,
3b + 7b = 10b
but there's a subtraction in the expression!
10b - b = 9b
Then we finish with our third term
6 + 5 = 11
Answer:
6b^2 + 9b + 11
