If a and B are non-zero real numbers with unequal absolute values, then the value of a / B + B / a () a is greater than 2, B is less than - 2 or greater than 2 C less than or equal to 2 D greater than - 2 or less than 2

If a and B are non-zero real numbers with unequal absolute values, then the value of a / B + B / a () a is greater than 2, B is less than - 2 or greater than 2 C less than or equal to 2 D greater than - 2 or less than 2

The answer is greater than 2 or less than - 2
a/b+b/a=(a²+b²)/ab
When AB > 0
a²+b²>2ab
a/b+b/a>2ab/ab=2
a/b+b/a>2
When ab
