The product of two consecutive positive odd integers is equal to 1 less than seven times the sum of the integers. Find the integers.
Answer provided by our tutors
the two consecutive positive odd integers can be written as
2x-1 and 2x+1, where x is positive integer
the product of two consecutive positive odd integers is equal to 1 less than seven times the sum of the integers
(2x - 1)(2x + 1) = 7(2x - 1 + 2x + 1) - 1
by solving we find and consider the positive roots
x = 7
