Question 8 : What is the largest positive integer such that n2+7n+12n2โnโ12 is also positive integer?
can be rewritten as
= 1 +
1 + = 1 +
n cannot be -3
has to be an integer
And this value has to be equal to 1, for n to be high
So,= 1
8 = n - 4
n = 12
The question is "What is the largest positive integer such that n2+7n+12n2โnโ12 is also positive integer? "
Choice D is the correct answer.
