Expand. $$2\cdot7b=14b$$

$$2\cdot-6=-12.$$

$$-5\cdot2b=-10b$$

$$-5\cdot-3=15$$

Add up all the terms and get...

$$4b+3$$

To simplify this expression, first expand the four terms(in total) in the parantheses. When expanded, you get 14b - 12 - 10b + 15. Simplify this to get 4b + 3.

The simplified expression is 4b+3.
