By calculating the discriminant of the equation and if it's negative the equation will have no solutions
If the discriminant is positive, as in this case, there are two real solutions.Also: * If the discriminant is zero, there is one real solution, considered to be a "double solution" because of the way polynomials are factored. * If the discriminant is negative, there are two complex solutions, which are complex and non-real.
If the discriminant of a quadratic equation is less then 0 then it will have no real solutions.
240 is not an equation and so the concept of solutions is meaningless.
