Step-by-step explanation:
If we are given the quadratic model, we know that the height of anything on the ground is 0 meters, so that model becomes
I changed your x's to t's since t is for time.
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.
