Answer:

#8b^2-34b-30#

Explanation:

We must ensure that each term in the second bracket is multiplied by each term in the first bracket. This can be achieved as follows.

#(color(red)(8b+6))(b-5)#

#=color(red)(8b)(b-5)color(red)(+6)(b-5)#

now distribute the brackets.

#=8b^2-40b+6b-30#

collecting like terms gives.

#8b^2-34b-30#
