The position of an object moving in a straight line is given by s=2tsquared - 3t, where s is in meters and t is the time in secoonds the object has been in motion. How long (to the nearest tenth) will it take the object to move 19 meters?

\n" ); document.write( "s(t) = 2t^2-3t
\n" ); document.write( "19 = 2t^2-3t
\n" ); document.write( "2t^2-3t-19=0
\n" ); document.write( "t = [3 +- sqrt(9-4*2*-19)]/4
\n" ); document.write( "t = [3 +- sqrt(161)]/4
\n" ); document.write( "t = [3 +- 12.6886]/4
\n" ); document.write( "Positive answer:
\n" ); document.write( "t = [3+12.6886]/4
\n" ); document.write( "t = 3.9221 seconds
