Welcome.
00:02
We are here today to solve this expression using the completing the square method.
00:08
To follow along, i highly recommend that you use the six -step process outlined on page 677 of your textbook to aid you in this process.
00:19
Step one asks us to verify that the coefficient of our second degree term is in fact one, and we can see here that it is.
00:27
Step 2 asks us to move all constants to the right -hand side of the equation.
00:33
And as you can see here, that has already been given to us.
00:37
Step 3 then asks us to find half of our first degree term.
00:43
So here, our first degree term is negative 4.
00:46
So i'm going to write it off to the side.
00:48
Negative 4 divided by 2 is equal to negative 2.
00:52
Negative 2.
00:53
Negative 2.
00:54
And then step 4 asks us to square that value.
00:57
Value, we're going to square that of value, and we find that we have a value of four.
01:05
Step 5 then asks us to add this value to both sides of our expression...
