So this is common we're going to be solving by factoring.
00:03
Now the whole thing is already factored.
00:04
So what we do next is take each little piece and set them equal to zero.
00:08
If three things are going to multiply to get a zero, then one of these has to be zero.
00:12
So we're solving for this variable that makes that happen.
00:15
Now over here, where i put two equals zero, this doesn't make sense.
00:18
So there's no way this can be part of the solution.
00:21
Gcfs or numbers out front, again, are often disregarded.
00:25
So then from there we can solve the next one.
00:27
This gets us a w is equal to negative seven, because we're going to subtract 7 from both sides.
00:32
For this one, first we're going to have to do minus 10 on both sides, and then we're going to divide.
00:36
So we do end up with a fraction of negative 10 thirds.

We have two answers here...
