I messed this one up.... my math is wrong
Find the coordinates of the center and radius of the circle.
So I like to rewrite it
then I write it as the standard circle equation
So If I did this right I should have
and then my
Please I need someone to confirm to me I did this properly?
Side note is expanded to and I move the 16 over to the other side of the = sign in the equations.
You are correct to rewrite as:
Now, we want to complete the square on x and y. Whatever we add to the left side, we must add to the right.
Now, write everything as squares:
From this, we know the center is (4,-5) and the radius is 6.
