Question

How do you complete the square?

Answer 1

Post a question and I will walk you through it :)

Answer 2

x^2 + y^2 + 2x -2y -4 = 0

Answer 3

eg: x^2+10x+30

How do we make this into a perfect square?
x^2 + 10x + (0.5x10)^2 +/- x
= x^2 + 10x+ 25 - 5
= (x+5)^2 -5

It's a little hard to explain, did you understand this?

Answer 4

I have to do the same thing. I have to plot the points and find the slope of the line passing through the pair of points.
(-4,5,6) , (2,1,3)

Answer 5

I'm working on equations for cirlcles

Answer 6

Oh, that's different. I'm not too familiar with it, you need to put it in:
(x+a)^2+(y-b)^2 = c
Sorry ):

Answer 7

Thanks for trying

Answer 8

I will give it a try.
