@cheetah21 Can you do that or do you need further help?

I do need further help..sorry im just really bad with math :/

Okay how do we do that ?

x2 + 2x + y2 + 4y = 20
(x2 + 2x) + (y2 + 4y) = 20

Oh okay im sorry , i was confused i guess :/ so now do we need to solve in the parentheses or what ?

Would that be 1 also?

so then that would be 2 ?

oh 4 ?

(x+1)^2 = (x-4)^2 (are they equal?)

(5x)=(25x)

no wait typo

Can you try finding k from:
(y+2)^2 = (y-k)^2 ?

okay so then -4

You would take the square root on both sides, so
(y+2) = y-k,
can you solve for k?

(3) = yk
3yk
Im sorry if thats a dumb answer i just dont know

put it up, and perhaps someone else will look at it for you. I have to go now, sorry! :(

Its okay, thank you for all your help!

no problem! :)
