Question

find y / solve equation

3y^4-9y^2+2=0

Answer 1

good luck

Answer 2

lol, gee thx

Answer 3

you can use the quadratic formula to find \(y^2\) since this is a quadratic in \(y^2\)
or else put
\[3x^2-9x+2=0\] solve that one, then replace \(x\) by \(y^2\) and solve again

Answer 4

kk ill try that

Answer 5

unless there is a typo there, this problem was not cooked up to factor
you are going to get
\[x=\frac{9\pm\sqrt{57}}{6}\]

Answer 6

which is actually two solutions
then take plus or minus the square root of those for a total of four solutions
