(5b-1)(b+6)

To multiply (5b-1)(b+6), you can use the distributive property.

First, distribute 5b to both terms in (b+6):

(5b)(b) + (5b)(6)

Then, distribute -1 to both terms in (b+6):

(-1)(b) + (-1)(6)

Simplify each term:

5b^2 + 30b - b - 6

Combine like terms:

5b^2 + 29b - 6

Therefore, (5b-1)(b+6) is equal to 5b^2 + 29b - 6.
