Completing the Square Calculator
Solve quadratic equations using the completing the square method with our calculator.
What is the Completing the Square Calculator & How does it work?
The completing the square method is a technique used to solve quadratic equations of the form ax2 + bx + c = 0. By transforming the equation into a perfect square trinomial, we can easily find the roots of the equation.
The steps involve moving the constant term to the other side of the equation, completing the square on the left side, and then taking the square root of both sides. This method is particularly useful when the quadratic formula or factoring are not straightforward options.

ax2 + bx + c = 0 Rightarrow a(x + frac{b}{2a})^2 = -c + frac{b^2}{4a}
a = coefficient of x2, b = coefficient of x, c = constant term
