    The value of the discriminant in this equation is (-4) ^2-4*1*5 which is - 4

    Just for reference;

    If the value of the discriminant is negative, the equation has no real solution

    If the value of the discriminant is positive, the equation has two real solutions

    If the value of the discriminant is zero, the equation has one real solution.

    Therefore, the discriminant is - 4, so the equation has no real solutions
