A red ball anda green ball are simultaneously tossed into the air. The red ballis given an initial velocity of 96 feet per second, and itsheight tseconds after it is tossedis 16 t 2 96 t feet. The green ball is given an initial velocity of 80feet per second, and its height t seconds after it is tossed is 16 t 2 80 t feet.a)Find a polynomial D(t) thatrepresents the difference in the heights of the two balls.
b) How muchhigher is the red ball 2 seconds after the balls are tossed?
I have no idea how to goabout this. If anyone can explain how to do this and give solutionI would be very greatful.

a) D ( t ) = ( 16 t 2 + 96 t ) ( 16 t 2 + 80 t ) = 16 t
b) After 2 seconds, the difference in the heights of the twoballs is D(2).
Hence D(2) = 16(2) = 32 feet.
