Question

Find Two consecutive multiple of 6 whose product is 720

Answer 1

Define x:

Let one of the number be x

The other number is x + 6

Solve x:

The product is 720

x(x + 6) = 720

x² + 6x - 720 = 0

(x - 24)(x + 30) = 0

x = 24 or x = - 30(Rejected, since it negative)

Find the numbers:

one number = x = 24

The other number = x + 6 = 30

Answer: The numbers are 24 and 30

Answer 2

6*4=24

6*5=30

24*30=720
