When there are no intersection points of the graph with the x-axis, we get not real solutions (or 2 complex solutions). When there is 1 intersection point of the graph with the x-axis, there is 1 solution to the quadratic equation. When there are 2 intersection points of the graph with the x-axis, there are 2 solutions to the quadratic equation. The solutions to the quadratic equation are the roots of the quadratic function, that are the intersection points of the quadratic function graph with the x-axis, when The quadratic function is a second order polynomial function: This expression is important because it can tell us about the solution: The quadratic formula with discriminant notation: This equation is known as the Quadratic Formula. The expression inside the square root is called discriminant and is denoted by Δ: If you complete the square on the generic equation ax2 + bx + c 0 and then solve for x, you find that.

The discriminant is the part of the quadratic formula found within the square root. The solution to the quadratic equation is given by the quadratic formula: What is the Discriminant of a Quadratic Equation. ( x - x 1)( x - x 2) = 0 Quadratic Formula We can change the quadratic equation to the form of:

The solution to the quadratic equation is given by 2 numbers x 1 and x 2. Quadratic equation is a second order polynomial with 3 coefficients - a, b, c. The Quadratic Formula and the GED Calculator Weiss Videos 9.
