So first thing we are going to do is we're going to multiply this entire thing by three.
00:22
So it now becomes x squared minus 3x equals 5, which is converting the 5 over, setting equal to 0 to make it x squared minus 3x minus 5.
00:33
So our variables are 1, negative 3, and negative 5.
00:37
So now we're just going to plug it into our equation.
00:40
So negative b plus and minus the squared, negative 3 squared minus 4 times 1 times negative 5 over 2 times 1.
00:53
X is equal to 3.
00:55
I'm just going to simplify this up a bit.
00:59
9 minus 20 or 9 plus 20.
