To solve it, make one side of the equation equal to zero, factor the other side, then set each factor equal to zero and solve the resulting “mini equations.” Examples: What two numbers have a product of 6 and a sum of -5? Answer: -2 and -3. (6)(-15) = -90; What two numbers have a product of -90 and a sum of +1? Answer: +10 and -9.
