The solutoin so x^2 - 5x - 6 < 0 is -1 < x < 6, so the set of all possible values of x^2 + 5x + 6 is (2,72).

The question specifies that the real number x satisfies x^2 - 5x + 6<0 (not x^2 - 5x - 6 < 0).

This means x is in the range from 2 to 3. Substitute these values into x^2 + 5x + 6 to find the end points of the required set of values.
