The trick to this problem is to find the greatest common factor minus 2k to the 6 and then minus 15 k square, k to the fifth, excuse me, m square.
00:18
Let me double check if that's right.
00:20
Because you want to look for a greatest common factor.
00:23
And with the one in front, the numbers don't have a common factor besides one.
00:28
But if you look at everything else, there's five ks, at least five ks in every other part.
00:35
Like there's six ks on the next one.
00:37
Now the next one only has five ks.
00:39
But i like to write it out because then you can see what's left over after you factor out a k to the fifth.
00:48
And if you distribute k to the fifth back into it, you need to get back to that original problem.
00:53
So 2km and then you have that 15.
00:56
Let's see you factored out all five of those ks...
