Question

solve 5x^2-y^2=0
3x^2+4y^2=0

Answer 1

y^2=5x^2, then i get 100x^4+3x^2=0

Answer 2

second isn't correct ! right hand shouldn't be zero.

Answer 3

thats how its stated in the problem

Answer 4

wrong

Answer 5

sorry, I thought you typed it differently! \[y = \sqrt(5) x\]

Answer 6

how come?

Answer 7

and for the second part, \[y = 1/2 i \sqrt(3) x\]

Answer 8

no, you doing it wrong

Answer 9

what do you mean? that's the answer I'm pretty sure, or are you just trying to simplify?

Answer 10

they are both circles with radius of 0 so isn't the answer (0,0)?

Answer 11

yes that's the integer answer

Answer 12

the answer for the variable y is what I posted

Answer 13

no, you should solve for x and y, and you are solving it only for y

Answer 14

then yes, x = 0 and y = 0

Answer 15

alright
