Bunuel : I tried plugging in different integers greater than 3 in the expression x(x-2)(x+5) and found that the products are divisible by 3. However is there a deduction by which we can be sure for all values of x>3?
I only know the property that out of any three consecutive integers , at least one is definitely divisible by 3
How do I apply that in above case
