Okay, in order to solve for s, we first need to isolate the radical, which means to divide both sides by three.
00:11
So we had s over 3 equals the square root of s minus 2.
00:16
And then to get rid of the radical, you want to square both sides.
00:22
So squaring gets rid of the square root.
00:25
And you'll have s minus 2 on this side and square the s and square the 3.
00:32
Now what i would do is i would multiply both sides by 9.
00:39
And then i would distribute the 9.
00:44
And then i would get everything on one side.
00:46
So i'm going to subtract the 9s and add the 18.
00:51
And then you're going to try to factor.
00:56
So s squared, s, and s.
00:59
18.
01:00
I'm going to do 6 and 3, and it's minus 6 and minus 3.
01:05
And now since you're multiplying two things and the answer is zero, you set each item equal to zero because one of them has to equal zero.
01:14
And you get two possible answers of six and three...
