Cubic factoring: 3x^3 +2x^2 +75x-50=0 solve for x

3x^3 +2x^2 +75x-50=0 solve for x.

If i could get some direction on this i attempted to factor by grouping but no luck.

oh boy well this is the question you get in a correspondence book i guess. I was thinking it was a typo because if the 50 was positive instead of negative its much easier.
