Question 76771: HEIGHT OF A DIVER: a diver jumps from a diving board that is 32 feet above the water. the height of the diver is given by
height = -16( t - 2 )( t + 1 )
where the height is measured in feet, and the time t, is measured in second. when will the diver hit the water? can you see a quick way to find the answer? explain.
PLEASE HELP ME!!! PLEASE!!!

You can put this solution on YOUR website!
Think about the height of the diver when he/she hits the water! The diver's height will be zero feet. So, you can set height in the equation to zero and solve for t.
0+=+-16%28t-2%29%28t%2B1%29 Apply the zero products principle.
0+=+%28t-2%29%28t%2B1%29
So, when height is zero, t = 2 or t = -1
The only answer that is meaningful here is t = 2 seconds.
