Physics(Please help)

using the equation
y=yo + (vo sin Q) t - 1/2gt^2 I have to find t. The values for y, yo and vo were given to me.

So I set the equation up like this:
0=1.005 + (3.107 sin 0) t - 1/2(9.8)(t^2

The sin of 0 is 0 times 3.107 is 0.

So 0 = 1.005 t - 4.9 t^2

Now I am stuck. I am not sure how to solve this part. Thank you for your help!

    This is the same equation as before just with different numbers. y=yo + (vo sin Q) t - 1/2gt^2 This time the numbers are: 0 = 1.005 + (3.021 sin 30)t - 1/2(9.8)t^2 4.9t^2 - 1.5105 - 1.005 = 0 This is the part where I am stuck. Did
