Find the range of values which has no real solutions I would like to know how to solve the following problem:

Find the range of values of the parameter $m$ for which the equation $2x^2 - mx + m = 0$ has no real solutions.

I know I have to use the quadratic formula and the response is $0 < m < 8$.
But what I don't know is how to proceed to find this answer. Thanks for your help.

*

*A quadratic equality has no real solution if and only the discriminant is negative.

*First, find the discriminant, find out when is it negative.
