The expression has 2 factors, and the second factor has 2 terms.

<h3 /><h3>How many factors has the expression?</h3>

We can write an expression of N factors as:

$y = A_1*A_2*...*A_n$

Here, the expression is:

4*(8x + 5)

This expression has 2 factors, which are:

4 and (8x + 5)

Now, if we look at the only factor 8x + 5, we have two terms (the terms are the parts that are added), the terms are:

8x and 5.
