$b - 42$ $b-42$

Explanation:

Distribute the $- 7$ $-7" "$ (multiply $- 7$ $-7$ by each term in the parantheses)
$- 7 (b + 6) + 8 b$ $color(red) (-7(b+6))+8b$
$(- 7) (b) + (- 7) (6) + 8 b$ $color(red)((-7)color()((b))+(-7)(6)+)8b$

Simplify:
$- 7 b - 42 + 8 b$ $-7b-42+8b$

Combine like terms:
Since $- 7 b$ $-7b$ and $8 b$ $8b$ are like trms, we can add them to get $1 b$ $1b$ or just $b$ $b$
$b - 42$ $b-42$
