The expression -x2 + 2x + 3
represents the height of a ball x
seconds after it was thrown. what
are the zeros of the expression and
what do they represent in
context?

Step-by-step explanation:

0 = -x² + 2x + 3

0 = x² − 2x − 3

0 = (x − 3) (x + 1)

x = -1 or 3

These represent the times that the ball's height is 0.  Since negative time doesn't make sense in this context, we would ignore it and say that the ball lands after 3 seconds.
