Standard #: MA.912.A.1.8Archived Standard This document was generated on CPALMS - www.cpalms.org Use the zero product property of real numbers in a variety of contexts to identify solutions to equations. Subject Area: X-Mathematics (former standards - 2008) Grade: 912 Body of Knowledge: Algebra Standard: Real and Complex Number Systems - Expand and deepen understanding of real and complex numbers by comparing expressions and performing arithmetic computations, especially those involving square roots and exponents. Use the properties of real numbers to simplify algebraic expressions and equations, and convert between different measurement units using dimensional analysis.

(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? page 1 of 1
