Completing the Square Calculator
Effortlessly solve quadratic equations using our completing the square calculator.
What is the Completing the Square Calculator & How does it work?
Completing the square is a method used to solve quadratic equations of the form ax2 + bx + c = 0. The goal is to rewrite the equation in the form (x + h)2 = k, where h and k are constants.
To complete the square, follow these steps: 1) Divide all terms by a (the coefficient of x2). 2) Move the constant term to the right side of the equation. 3) Add the square of half the coefficient of x to both sides. 4) Factor the left side as a perfect square trinomial.
