Use the zero product property of real numbers in a variety of contexts to identify solutions to equations.
Remarks
Example 1: Solve for x.
(x + 5) ( x - 1) = 0
Example 2: Solve for x.
x³ - x² - 2x + 2 = 0
Example 3: A ball is kicked and flies through the air according to the following function: h(t)= -16t^2+47t+3, where h is the height of the ball (in feet) and t is the number of seconds after the ball is kicked. At what time, t, does the ball hit the ground after being kicked?
