2. Relevant equations

I think that i need to complete the square and then use, x=sec u, dx=sec u tan u du

3. The attempt at a solution

i have attempted various methods but none has yield the right result :S

ive gotten

X^2/((x-1/3)^2-16/9)^(3/2)

then i used U=x-1/3

(u+1/3)^2/(U^2-16/9)^(3/2)

then i use u=(4/3)sec o and du=(4/3)sec o tan o do

and i get

((16/9)(sec o )^2 + (8/9)sec o + (1/9))/(64/27)(Tan o)^3

and i dont know where to go from there b/c the methods i have used have not worked
