Our section is on solving by completing the square.
00:03
So to do that, we will first add the six to both sides, giving us v squared minus 5v equals 6.
00:14
We will then complete the square, which recall means putting the third number in the trinomial, which is half of the middle coefficient squared.
00:25
So we have negative 5 over 2 squared, which would be 25 .5.
00:31
And we will add that 25 fourths to the right side as well.
00:39
On the left side, that would be v minus 5 over 2 squared, because half of the negative 5 is 2.
00:51
And on the right side, 6 is the same thing as 24 over 4.
00:57
So i really have 24ths plus 25 4ths or 49 fourths.
01:05
To get v by itself.
01:09
I'm going to have to take the square root of both sides...
