Question

Math Check please :)!

\[6x ^{4}-11x ^{2}+3=0\]

I got 1/3,3/2

Answer 1

did you let z = x^2 (or something like that)? If so, then you found the solutions for z, but not x

Answer 2

Yeah, looks like that's what happened :) ^^^

Answer 3

you are right, x = (1/3) and (3/2)

Answer 4

so you need to solve x^2 = 1/3 and x^2 = 3/2


Note: you should get 4 solutions

Answer 5

wait nevermind
