Then the formula will help you find the roots of a quadratic equation, i.e. the values of x where this equation is solved. The quadratic formula x = − b ± b 2 − 4 a c 2 a
This quadratic equation root calculator lets you find the roots or zeroes of a quadratic equation. A quadratic is a second degree polynomial of the form: ax^2+bx+c=0 where a\neq 0 . To solve an equation using the online calculator, simply enter the math problem in the text area provided.
May 15, 2024 · The quadratic equation has only one root when Δ = 0. The solution is equal to x = -B/2A. It is sometimes called a repeated or double root. The quadratic equation has no real solutions for Δ < 0. You can also graph the function y = Ax² + Bx + C. It's shape is a parabola, and the roots of the quadratic equation are the x-intercepts of this function.
Aug 3, 2023 · How to Find the Roots of a Quadratic Equation. We can solve the quadratic equation to find its roots in different ways. Using the Quadratic Formula. As we know α and β are the two roots of the quadratic equation, whose values can be determined using the quadratic formula: (α, β) = − b ± b 2 − 4 a c 2 a.
The formula to find the roots of the quadratic equation is x = [-b ± √(b 2 - 4ac)]/2a. The sum of the roots of a quadratic equation is α + β = -b/a. The product of the Root of the quadratic equation is αβ = c/a. The quadratic equation whose roots are α, β, is x 2 - (α + β)x + αβ = 0.
