The first thing we need to do in order to solve this equation is to factor the quadratic expression.
00:07
So this is going to factor out to be x plus 3 and x plus 4 equals 0.
00:19
So now that we have the factors, we're going to take each one of those factors and set them equal to 0.
00:26
So we have x plus 3 equals 0 and x plus 4 equals 0.
00:33
So since we have two factors, we have two equations, which means we'll get two solutions.
00:40
So we'll solve for x.
00:42
We get x equals negative three for our first solution, and then x equals negative four for our second solution.
00:54
And now we just need to check our answers.
00:58
So we're going to start with our first solution of negative three, and we're just going to take that all the way back to the original equation and place.

It in for each of our x's...
