WebIn mathematics, completing the square is used to compute quadratic polynomials. Completing the Square Formula is given as: ax 2 + bx + c ⇒ (x + p) 2 + constant. The quadratic formula is derived using a method of completing the square. Let’s see. Given a quadratic equation ax 2 + bx + c = 0; Isolate the term c to right side of the equation We can complete the square to solve a Quadratic Equation(find where it is equal to zero). But a general Quadratic Equation can have a coefficient of a in front of x2: ax2+ bx + c = 0 But that is easy to deal with ... just divide the whole equation by "a" first, then carry on: x2+ (b/a)x + c/a = 0 See more Say we have a simple expression like x2 + bx.

WebAny quadratic equation can be solved by completing the square. After completing the square, move the constant terms so that they are on a different side of the equation to the squared brackets to get (𝑥 + a) 2 = k. Then square root both sides to get 𝑥 + a = ±√k. Subtracting a from both sides gives the solution as 𝑥 = -a ±√k.
