Okay, so we're asked to find the unknown in this problem, and the unknown is y.
00:09
And so if we're trying to get y by itself, it's advantageous to get y squared by itself first.
00:14
So the first thing i would do is subtract 24 over, just kind of nice.
00:18
Zero minus anything is just the negative of that piece.
00:22
I'm going to leave this three -fourths alone.
00:26
And i was always taught to get rid of a fraction you multiplied by the reciprocal.
00:31
Now, you could divide both sides by three -fourths, but divided by three -fourths.
00:34
Is the same thing as multiplying by four thirds.
00:39
You can see the fours would cancel here.
00:41
The threes are canceled.
00:42
So you are left with y squared.
00:44
I would do this in my head by thinking about 24 divided by three first is eight times four.
00:52
Give me negative 32.
00:54
That's just how i would do the math in my head...
