The product of two consecutive odd integers is 6 more than 5 times the smaller number, find both numbers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The "solution" in the post by @mananth is INCORRECT,
since he incorrectly solved the quadratic equation.
See my reasoning below.
Let 'n' be the smaller of the two odd consecutive integers.
Then the greater add consecutive integer is (n+2).
Our equation is
n*(n+2) = 5n + 6,
n^2 + 2n = 5n + 6,
n^2 - 3n - 6 = 0.
The discriminant is d = b^2 - 4ac = (-3)^2 - 4*1*(-6) = 9 + 24 = 33.
= is not an integer or a rational number,
so integer 'n' as described in the problem, does not exist.
ANSWER. As posed/printed/presented in the post, the problem HAS NO solution.
