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
