Me with this!
show that {1,2} ⊆ {x|x^4 - x^3 - x^2 - 5x + 6 = 0}

The set is the set of all values of that are solutions to the given equation. So all you need to do is check whether and satisfy the equation.

The equation holds, so both 1 and 2 are solutions, and hence is a subset of the solutions.

95.03 is the answer. hope this !
