How do I go about answering this question? Show that the equation has a solution for all values of and . I think I have to use the discriminant, but I'm not sure how.

yes. You are right. The discriminant is {(a+b)^2 - 4ab} = ....?
Oh, nevermind I got it now. Since is squared, the answer will always be positive, hence the reason why there are solutions for all values of and ?
