Directions: Use only the digits 1-9, each digit only once, create a problem that has the solutions x = 4 and x = -1/2.
How does the Zero Product Property help us rewrite this equation?
What would the parameters need to be in the first factor to result in a solution of x = 4?
Most commonly found student answer: (1x + -4)(2x + 1) = 0.
