The way to solve these kind of questions is to first bring all the terms to one side of the equation.
Depending on what the question is looking for, you equate the discriminant (b^2 - 4ac) to be either less, equal or more than zero. Thereafter, solve that equation to obtain the range of values!
Hope this helps! If it is unclear, do feel free to clarify further :)
