50= -4.9t^2 + 38t + 1.75...SOLVE?PLEASE TYPE IN FULL.
4.9T^2-38T+48.25=0 ..AS PER STD.EQN....AX^2+BX+C=0....A=4.9...B=-38....C=48.25
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%2838+%2B-+sqrt%28+38%5E2-4%2A4.9%2A48.25+%29%29%2F%282%2A4.9%29+
x+=+%2838+%2B-+22.32+%29%2F%289.8%29+
X=6.16...OR.....1.6
