Let x represent the first number; Then, the other is (5 − x) , since their sum is 5 and their product is 14 x(5 − x) = 14 5x − x2 = 14 x2 − 5x − 14 = 0 (x2 − 7x) + (2x − 14) = 0 x(x − 7) + 2(x − 7) = 0 (x − 7)(x + 2) = 0 Either (x − 7) = 0 or (x + 2) = 0 x = 7 or x = − 2 The two numbers are 7 and − 2
