Mathway requires javascript and a modern browser. We can help you solve an equation of the form "ax2 + bx + c = 0" algebra/images/quadratic-solver.js Is it Quadratic?Only if it can be put in the form ax2 + bx + c = 0, and a is not zero. The name comes from "quad" meaning square, as the variable is squared (in other words x2). These are all quadratic equations in disguise:
How Does this Work?The solution(s) to a quadratic equation can be calculated using the Quadratic Formula: The "±" means we need to do a plus AND a minus, so there are normally TWO solutions ! The blue part (b2 - 4ac) is called the "discriminant", because it can "discriminate" between the possible types of answer:

How do you find a quadratic equation whose roots are given?The formula to find the roots of the quadratic equation is x = [-b ± √(b2 - 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 x2 - (α + β)x + αβ = 0.
Can a calculator do the quadratic formula?Calculator Use
The calculator solution will show work using the quadratic formula to solve the entered equation for real and complex roots. Calculator determines whether the discriminant (b2−4ac) is less than, greater than or equal to 0. When b2−4ac=0 there is one real root. When b2−4ac>0 there are two real roots.
What is the quadratic equation whose roots are A and B?A quadratic equation, whose roots are α and β can be written as (x−α)(x−β)=0=x2−(α+β)x+αβ
