Solve the following equation by completing the squareĭetermine the square roots on both sides. Rewrite the quadratic equation by isolating c on the right side.Īdd both sides of the equation by (10/2) 2 = 5 2 = 25.ĭivide each term of the equation by 3 to make the leading coefficient equals to 1.Ĭomparing with the standard form (x + b/2) 2 = -(c-b 2/4)Ĭ – b2/4 = 2/3 – = 2/3 – 25/36 = -1/36Īdd (1/2 × −5/2) = 25/16 to both sides of the equation.įind the square roots on both sides of the equation The standard form of completing square is Solve by completing square x 2 + 4x – 5 = 0 Transform the equation x 2 + 6x – 2 = 0 to (x + 3) 2 – 11 = 0 Solve the following quadrating equation by completing square method: Now let’s solve a couple of quadratic equations using the completing square method. Isolate the term c to right side of the equation Given a quadratic equation ax 2 + bx + c = 0 The quadratic formula is derived using a method of completing the square. ![]() Completing the Square Formula is given as: ax 2 + bx + c ⇒ (x + p) 2 + constant. In mathematics, completing the square is used to compute quadratic polynomials.
