I have already solved this before. You've asked the same question lol, search for the old one ^_^
oh wait, it's different ^^" my bad.
yea the y^2 is throwing me off.
i came up w/ x=(-1,-3) y=(2,0) but im not sure thats right...
Alright, first of all, call your equations as (a) and (b). Now, let's re-write equation (b) in terms of y and we'll get: y = 3 + x Substitute this equation in (a) and you'll get: \[x^2 + 2(3+x)^2 - 9 = 0\] \[x^2 + 2(3+x)(3+x) -9 =0\] \[x^2 + 2x^2 + 12x + 18 -9 = 0\] \[3x^2 + 12x -9 = 0\] \[(3x-3)(x-9) = 0\] so x = 1 and x =3 Plug these 2 x's in equation b and find the 2 points ^_^ give it a try now :)
Your points should be (1,4) and (3, 6) :)
DOn't you mean x = 1 and x = 9
lol right right! >_< thank you :)
oh dear , I messed up again the equation should be: (3x-3)(x-3) = 0 instead of (x-9)
so you have x = 1 and x = 3 ^^" sorry lol
plug these in equation (b) and you'll get (1,4) and (3,6) as your points :)
and thank you blexting :)
it wouldnt be (1,4) and (3,12)?
no ,it'll be (1,4 ) and (3,6) I made a silly mistake in the previous last line where I have put: (3x -3)(x-9) = 0 it should be : (3x -3)(x-3) = 0 instead :)
plug x = 3 in the equation and you'll get the other point (3,6) ^_^
ok I see. that x-9 was throwing me off. Thans for your help!
np :) again, sorry for the mess ^^"
Wait. x^2+2x+12+18-9=0 wouldnt this simplify to 3x^2+2x+9=0 ?
you have negative 9
oh right! >_< again sorry lol
yo'll have negative 3 and not 9
Ok I think i have it.
when i solve I keep coming up with x=(-1,-3) y=(2,0)?
y=2 and x=1
or y=0 and x=3
yes! excellent js! :)
I'll give you a star ^_^
a star from me too
i mean y=0 and x=-3
lol abigail :)
i know what you mean, dont wory
thank you for your support too ^_^
you know what I mean?
i know what i know
so, what did I mean?
I know what you know I know
._. ...now I don't even know what I have said
i know you dont know what you think you dont know
I don't even know what I know now x_x
Well guys i know i appreciate the help:)
np js :)
i know it is
I don't even know what is what right now, but I do know that the word "know" sounds funny nowx_x
just say "know" 29 times out loud, and then pause for 5 sec, and say it again, and i promisse, it will sound weird
go finish your 5 $ work =P
finished all the orders already
made a fortune
atleast you had fun :)
This solution was very difficult to follow. I hope js14 understands the final answer is x=-3, y=0
