To begin this, we're going to solve by completing the square.
00:03
We're going to move that 10 to the other side.
00:05
So it becomes minus 22x equals negative 10.
00:08
So now i'm ready to do the b over 2 squared, so it would be negative 22 over 2 squared, which is 121.
00:15
So i'm going to add 121 over here.
00:17
I'm going to add 121 over here.
00:19
Now i'm going to head and factor the left.
00:21
So this is x minus 11 squared.
00:24
And then negative 10 plus 121 is 11.
00:27
I'm going to take the square root of both sides.
00:29
I get x minus 11 is equal to 111.
00:33
Now 111 is divisible by 3, but that gets you 37 and 3, and there's no other factors there, so we would be stuck there...
