Multiply.
(3b-5) (7b+1)
Simplify your answer.

It would be 21b² -32b -5

By using the FOIL method, you can simplify the equation.

The Foil Method is ac + ad + bc +bd, or First, Outer, Inner, Last.

First, you multiply the first term in each bracket.

3b * 7b = 21b²

Next, you multiply the outer term in each bracket.

3b * 1 = 3b

Then, you multiply the inner term in each bracket.

-5 * 7b = -35b

After that, you multiply the last term in each bracket.

-5 * 1 = -5

Lastly, you combine like terms.

21b² + 3b -35b -5 ---> 21b² -32b -5

21b² -32b -5 would be your answer, since you cannot simplify the equation anymore.
