Rewrite the expression as a single fraction with no negative

Rewrite the expression as a single fraction with no negative exponents,and with numerator factored and all possible cancellations done. then find all x values which cause the expression to become 0
-3x^-4+2x^-6

-3/x^4 + 2/x^6

= (-3x^2 + 2)/ x^6

-3x^2 + 2 = 0

x = (2/3),-(2/3)
