    We have been given an equation 0 = x^2-4x + 5. We are asked to find the discriminant of our given equation.    

    We will use discriminant formula to solve our given problem.

    D=b^2-4ac, where,

    D = Discriminant,

    b = Coefficient of x term,

    a = Coefficient of x^2 term,

    c = Constant.

    D=(-4)^2-4(1)(5)

    D=16-20

    D=-4

    When D is less than 0, then equation has no real solutions.

    When D is equal to 0, then equation one real solution.

    When D is greater than 0, then equation has two real solutions.

    Since -4 is less than 0, therefore, our given equation has no real solutions.
