i would start with $3x^3+4x+4=0$so make life easier

4. anonymous

then you can use the quadratic formula without all those annoying minus signs

5. Carter15

i think it would be -7x - 4 = o Then add the 4 to both sides That would be - 7x = 4 Then i would divide not sure though

6. Carter15

no wait thats not right sorry

7. Carter15

i was thinking it was a different kind of problem

$\frac{-2\pm2\sqrt{2}i}{3}$ looks good !
