At its core, the quadratic equation is a formula for finding the solutions to a quadratic equation of the form ax^2 + bx + c = 0. The quadratic formula is: x = (-b ± √(b^2 - 4ac)) / 2a. The discriminant, denoted by the letter "d", is the value under the square root, b^2 - 4ac. The discriminant determines the nature of the solutions: if d > 0, there are two distinct real solutions; if d = 0, there is one real solution; and if d < 0, there are no real solutions.
