Hi, so we're solving for the absolute value equation.
00:08
So absolute value means in here i want to make this either 5 or i want to make this negative 5 because the absolute value of negative 5 is 5.
00:23
So i need to get two answers.
00:25
First i need to get, well, what happens when i do x squared plus 1 equals 5.
00:33
Okay, so that becomes four and then i square root both sides.
00:41
So i square root here, this, and i get positive negative 2.
00:50
So now i want to get negative 5.
00:52
So x squared plus 1 is negative 5.
01:00
All right, we add one to both sides and then subtract 1.
01:12
Then i want the square root of that...
