The least value of the answer is 1.
Explanation:
Assuming x refers to 1 (the least possible positive number) and 1 is substituted to the values of x, x squared is equal to 1 multiplied by itself, resulting in 1. 1 plus 1 is equal to 2. The numerator will equal 2 if 1 is substituted in for x. The denominator equals 2 multiplied by x. x is equal to one, making the denominator equal 2. 2 over 2 in simplest form is equal to 1.
