Let's keep in mind first, what would be the formula that we would even use. But, when finding this in the first place, we would really need to consider why we would have to use this.
So, we would have to use this mainly because by using this of course, all we would practically do is to plug in the numbers, and from there, our answer would come very clear.
The formula:![\left[\begin{array}{ccc}V= \frac{4}{3} \pi r^3\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7DV%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%20%5Cpi%20r%5E3%5Cend%7Barray%7D%5Cright%5D%20)
So, by using this formula, lets then plug in some numbers.

<u>Answer:</u>
<u>Step-by-step explanation:</u>
32a^3 + 12a^2
To factorize this, start by taking the common variable out. As we have two powers for the same variable a, we can take the smaller power of a as a common to get like shown below:
32a^3 + 12a^2
a^2 (32a + 12)
Now when you have taken the variable as a common, try and take out a common number from the coefficient of a as well:
a^2 (32a + 12)
4a^2 (8a + 3)
So, the fully factored form of 32a^3 + 12a^2 is 4a^2 (8a + 3).
