Okay, this time they give us the equation 3 plus the square root of 2x minus 1 is equal to 0.
00:10
Well, let's see.
00:11
Let's bring the 3 over to the other side.
00:13
Negative.
00:14
Ooh, this one has no solution.
00:16
We know that for my previous word.
00:18
Problem is 15 to 18.
00:20
I can verify that for you.
00:21
Let's square both sides.
00:23
Since they should be the same number, we'll multiply both sides by the same number.
00:26
It should still be the same.
00:28
So solve for x.
00:30
We'll get 10 over 2, but that's just equal to 5.
00:33
Well, this is a possible solution, isn't it? it won't.
00:36
Okay...
