We're being asked to factor the given expression completely.
00:04
Remember, anytime you're asked the factor, always look for a greatest common factor first, which in this case there is none.
00:10
So let's look at how we can factor these two terms.
00:13
Well, it looks like they're both perfect cubes that are getting added together.
00:17
So we can factor this as the sum of two cubes.
00:20
So the first factor will have two terms in it.
00:23
To get the first term, we take the cube root of the first term.
00:27
Well, the cube root of x to the 6a power is just, x to the 2a power.
00:32
We just divide our exponent by 2, or sorry, by 3, because we're taking the cube root...
