WebIn this mini-lesson, we will explore about the nature of roots of a quadratic equation. You will learn about the nature of roots of quadratic equation using the discriminant formula, quadratic formula, roots of a cubic equation, real roots, unreal roots, irrational roots, imaginary roots and other interesting facts around the topic. WebThe expression inside the square root is called discriminant and is denoted by Δ: Δ = b2 - 4 ac The quadratic formula with discriminant notation: This expression is important because it can tell us about the solution: When Δ>0, there are 2 real roots x 1 = (-b+√ Δ )/ (2a) and x 2 = (-b-√ Δ )/ (2a). When Δ=0, there is one root x 1 =x 2 =-b/ (2a). osteomyelitis foot x-ray
