Homework Help: Algebra

Posted by Bethany on Friday, March 21, 2008 at 1:11pm.

HELP!
an object moves in a straight line given by s=2x^2-3t where s is in meters and t is the time in seconds the object is in motion. how long to nearest tenth will it take to move 17 meters?

my attempt
s=2t^2-3t
17=2t^2-3t
-17=-17
0=2t^2-3x-17
t=-b +or- sqrtb^2-4ac/2a
t=-(-3)+or-sqrt-3^2-4(2)(-17)/2(2)

Did I do all of the correct steps? I think I did but this is really confusing
