# How do you multiply #(2a + 2a^2)(3 + a)#?

##### 1 Answer

#### Explanation:

To multiply this polynomial, you must use the distributive property. Recall that a polynomial like

To use the distributive property in a polynomial like the one you gave, it helps to "simplify" it to an easier form. Let's let

Now we can use the familiar distributive property:

We now have

This gives:

We can see that we now have to use the distributive property again, twice this time. This gives:

Thus, our final answer is
