\[2(x-3)^2+2y^2=8\]
jimthompson5910 (jim_thompson5910):
try to get the equation into the form \[\Large (x-h)^2 + (y-k)^2 = r^2\]
OpenStudy (steve816):
I divided the entire equation by 2
jimthompson5910 (jim_thompson5910):
great start
OpenStudy (steve816):
I got \[(x-3)^2+y^2=4\]

then what?
OpenStudy (steve816):
Hmm, is this the standard form?
jimthompson5910 (jim_thompson5910):
yeah more or less. Do you see what the center is? what the radius is?
OpenStudy (jackthegreatest):
oo could i give the answer?
jimthompson5910 (jim_thompson5910):
let steve try it out

ok could i give a hint?
OpenStudy (steve816):
Oooh I think I figured it out, the center is (3, 0) and the radius is 2.
jimthompson5910 (jim_thompson5910):
correct
OpenStudy (steve816):
Thank you, but now I need to find the x and y-intercepts. How do I do that?
jimthompson5910 (jim_thompson5910):
@jackthegreatest yes you can give hints as that helps better than just giving the answer

: )
OpenStudy (jackthegreatest):
lol k
jimthompson5910 (jim_thompson5910):
to find the y intercept(s), you plug in x = 0 and solve for y
to find the x intercept(s), you plug in y = 0 and solve for x
OpenStudy (steve816):
Alright, thanks :)
jimthompson5910 (jim_thompson5910):
no problem
