Super easy! The discriminant of a quadratic equation ax^2 + bx + c = 0 is found using the formula b^2 - 4ac. Just plug in the values of a, b, and c, and you're good to go!
Just use b^2 - 4ac. Works every time!
First-hand experience here: Plugging in the values for a, b, and c into the discriminant formula b^2 - 4ac always gives me a quick read on the roots!
