You distribute the first set of brackets.
When you have equations like this you should pretend there are no brackets around the first equation.
b6 (b+3)
first you distribute b into the brackets.
(b)(b) = b^2
then b to 3
(b)(3) = 3b
then you distribute the 6 to both...
(6)(b) = 6b
then 6 to 3...
(6)(3) = 18
then you add them together...
b^23b18
