Basic Algebra/Solving Quadratic Equations/The Zero Product Property
Vocabulary
[edit | edit source]Lesson
[edit | edit source]The zero property is based on the elementary concept that when you multiply two numbers and the answer is zero, then one of the numbers multiplied must be zero.
Rule: if a × b = 0, then a = 0 or b = 0.
Meaning that the zero property establishes that a or b has to equal zero in order for the result to be zero, a or b could be any random number while the other variable is zero so that result would still be zero.
