Assignment 26
If a and b are real numbers, and ab = 0, then a = 0 or b = 0. In other words, if the product of two or more numbers is zero, then at least one of the numbers must be 0. This is an important real number property that can be used to solve quadratic equations. Remember: Factor means "write as a product." We can often solve equations using factoring. Example:
