Interesting problem here.
00:01
They want us to make a four -term polynomial and then i believe factor it.
00:07
Let me double check.
00:08
Yep.
00:09
Factor it.
00:09
So i think the easiest way to do this is know where we want to get to after they're grouped.
00:14
Like for instance, i just made one up, 3 y minus 2.
00:17
And i'll say this is where i want to get after i group them.
00:19
And so i know that i want this to be something y to the fourth, right? and so the only way to get that is i got to multiply by y to the third.
00:29
And, and, so i know that i want this to be something y to the fourth.
00:30
And so the only way to get that is i got to multiply by y to the third.
00:30
And, and, and why don't we just make it 2 y to the third? why not? and so we'll get our terms here, 2 y to the third times 3 y gives us 6 y to the fourth, 2 y to the third times a negative 2 is going to be a negative 4.

Negative 4 y to the third...
