Question

Amy and Sara's ages are consecutive even integers. The product of their ages is 528. If Sara is

younger, how old is Amy?
Write an equation that can be used to find their ages.

Answer 1

24

Explanation:

Sara = x age

Amy = x+2 when Sara x = 22 Amy is x + 2 = 24

Product of ages = 528 so............

x(x+2) = 528

x² + 2x - 528 = 0 solve for x I did it graphically first to get x = -24, 22

(x+24) (x-22) = 0

(x+24) = 0 (x-22) = 0

x = -24 x = 22 since you really can't have a negative age
