Two options;

- Use the quadratic formula and then put your answer from that into the calculator and convert to decimal

- Use an alternate method to find the answer, such that you don't end up with a quadratic

Do it  by hand :P Scientific calc aint gonna help much.

If you got this by doing a motion question, you must be overlooking something as they ALWAYS make it so you don't have to use quadratics.
