How would I algebraically solve for the zero with the function h(t)=-4.9t^2+9.42t+1.95? t=2.11 

Use your calculator to find the zero of the function. Verify the time the ball took to hit the ground by
algebraically finding the zero. Show your work below:
(2.11,0)
CITY₁
0 = - 4. 9(+-0,96)² +6.47
-6.47
-6.47
6.47 = -4/9(4-0.96)²
