Question

Write the expression in complete factored form.
5a(b + 1) + 3(b + 1) help

Answer 1

(b+1)(5a+3)

Explanation:

Notice how (b+1) appears on both sides. That means we can "factor it out" by moving it to the very left -

(b+1)

Now we know the form of the answer we can continue doing it.

For the next step, I take the terms 5a and 3 (what's left) and move them to the right as shown:

(b+1)(5a+3)
