Now we need to factor that quadratic and solve for time:

Since -2 definitely does not equal 0, then

Factor that and find t values of 4 and -2. Again, we know that time will never be negative, so
t = 4 seconds.
B. Y equals 0, because if you plug it in ( multiply 2 by 9 ) you will get 18-18 which equals 0.
