Problema Solution
The product of two consecutive cold integers Is 9 more than 10 times the smaller. Find the pair of integers.
Answer provided by our tutors
we assume "cold integers" should be read as "odd integers"
let '2n+1' represent the first odd integer, then "2n+3" represents the second
the product of these integers is 9 more than 10 times the smaller:
(2n+1)(2n+3)=10(2n+1)+9
solving for n we have:
n={-1,4}
2(-1)+1 = -1
2(4)+1 = 9
if we stick with positive-valued integers, the answer is (9,11)
