The discriminant basically tells you what kind of roots the quadratic equation has: real and distinct, real and repeated, or complex.
Simply put, it's b² - 4ac. Calculate it to figure out if the equation has real or imaginary solutions.
The discriminant? b² - 4ac. It's that simple!
I've used the discriminant tons of times in my physics homework. It's just b² - 4ac and helps me figure out if my solutions are real or complex.
