Question 1078541
integers are x and x+2
their product is x^2+2x=10x+9
x^2-8x-9=0
I think you used x and x+1 as consecutive odd integers.  Consecutive even and odd integers are x and x+2 in both instances
(x-9)(x+1)=0
9 and -1
integers 9 and 11, product is 99 and that is 9 more than 10*9
-1 and 1, and their product is -1, which is 9 more than 10(-1).
Two sets of integers
