We're being asked to factor the given polynomial.
00:02
Remember, when factoring, you should always start by looking for a greatest common factor.
00:07
In this case, we do have a greatest common factor of negative 5y.
00:11
And the reason why i'm having it be negative is because we always want to have this first term be positive when we factor.
00:17
So now, let's go ahead and divide each term by our greatest common factor.
00:21
Well, negative 5y to the 3rd divided by negative 5y is positive y squared, and 20 y divided by negative 5y is negative 4.
00:31
Now, we have to see if we can factor further.
00:34
Well, i notice that both our terms are perfect squares, and they're getting subtracted.
00:39
Therefore, we have a difference to squares problem...
