Best ResponseYou've already chosen the best response.2Find the value of the discriminant for each quadratic equation below. Show all steps needed to write the answer in simplest form, including substituting the values of a, b, and c in the discriminant formula. Then use the value to determine how many real number solutions each equation has. 2x^2 3x = 5

Best ResponseYou've already chosen the best response.2oh ok. would my final answer be 31?

Best ResponseYou've already chosen the best response.1Yes, so the discriminant is \(31\), which is negative. so how many real solution the given quadratic equation will be having ?

Best ResponseYou've already chosen the best response.2Since D is negative, root (D) doesn’t exist so the roots are unreal.

Best ResponseYou've already chosen the best response.1Awesome! so there are no real roots for the given quadratic equation

Best ResponseYou've already chosen the best response.0Okay so let me get this straight: So the asking person is asking this very confusing question which I DO NOT GET ANYMORE!!!! (Sorry for all caps). Ah... could someone teach me this stuff again? I know the powers pretty well but this particular problem like this. It's not like it's for homework anything but I really need help understanding this. I'm learning Geometry this year and I really just need some math help right now. Thanks!
