In all of these equations we are finding the factor for the answer. We are using grouping‚ GCF‚ prime factor‚ and perfect square as well in these set equations. Page 345 - 346 #52. Using (45) as the product and (18) as the sum. 18z + 45 + z^2 Equation (z + 15)(z + 3) Answer Breaking it down using the FOIL method to verify the answer: z * z = z^2 This is a perfect square. 15 * z = 15z z * 3 = 3z 15 * 3 = 45 In this equation to get the answer we need to use the GCF (Greatest Common
