Needed Help D:
Ok it's just two questions you have to answers! and please tell me how you got them. Thanks!
First Question
12-x^2 -2xy = 0
12-y^2 - 2xy = 0
For some reason x and y are both 2
I tried and got y= 6x -0.5x tried to sub into second one but gets messy any way to do this on a calculator by any chance I have a Ti-83 but I want to know/ how to do it algebraically.
Second Question
Solve each equation and check for extraneous solutions.
a) the root of w-3 = the root of 4w+15 (I can't make the root sign in this window)
b)the root of x^2-5x+2 = x2
c) (5y-3) = 1 + (y+7)/(2y-6)
Yours-Truly

SSorry I'm only in eighth grade.man that looks like a pain!
yeah...
Dear God! I'm going to hate whatever grade your in! I'm sorry but I'm only in seventh grade!
Um......................I would help you if I knew what the heck this is! But I'm horrible with math and have no clue what to do!!!
Sorry! :(
sorry,i would help but i suck at math :P my head hurts just looking at that!
O.O wtf?
At first I'm like, oh, math. :33
And then I was all,
Oooooohhhhnooooo.... }:[
:O Even I Don't do that yet.Sorry
12-x^2 -2xy = 0
So this is what I THINK (I'm only 11)
So x and y=2? Okay...
12-6-6=0
Because (2xy) is 2x2(x)x2(y)=6 and x^2=6 SO (12-6)-6=0. Get it? It may seem complicated and stuff, but its kinda easy.
Hope I helped!
I just read my comment, and it seems even more complicated when I try to explain it.. o.O
Yeah it did help, thanks!
Oh my gosh... that's insane. I'm glad you got help, though, because I wouldna been able to help xD
