So we're looking at solving for r in this problem, which we have 2r minus 3 squared minus 24 equals 0.
00:12
So before you solve, well, i guess the first step to solve is to get the quantity squared by itself.
00:21
And that's pretty easy to do because you can just add 24 over.
00:25
So 0 plus 24 is 24.
00:28
I can't do anything with this 2r minus 3 squared yet.
00:33
But now that we get to that point, we can square root on both sides.
00:37
So square root will cancel out with a square.
00:40
So on the left side you have 2r minus 3.
00:43
And on the right side, you would probably want to figure out that 24 is 4 times 6.
00:50
And then 4 can be broke down as 2 times 2.
00:53
So there's a pair of 2s that you can bring in front, plus 4...
