hi, I was wonderin how i would solve for X in the following equation...
[tex] 0 = 60x^2 - 90x^4 [/tex]
If i do add 90x^4 from both sides...and then go about solving for x, i get 1/x, which is the same as -x...and then i have to take the square root of a number, and i can't do that with a negative number. So.. yeah, i need help. my algebra skills are very rusty...thanks
