Remember that for any quadratic equation:
ax^2+bx+c = 0
The quadratic formula says that the two solutions will be:
x = -b/2a ± sqrt(b^2-4ac)/2a
What are a, b and c in this case?  
Try substituting in the numbers from your problem and seeing if you can work it out.  If you have trouble let me know and I will do my best to help.


Take it a step at a time Carlos, first identify a, b and c and then try to put them into the formula and only after that should you try to do the operations that lead to an answer.
