1. Understanding Completing the Square: Isoke Is Solving The Quadratic Equation By Completing The Square.

Completing the square is a technique used to transform a quadratic equation into a form that makes it easier to solve. It involves adding and subtracting a specific value to the equation in order to create a perfect square trinomial.

The general form of a quadratic equation is ax2+ bx + c = 0 . To complete the square, follow these steps:

  1. Move the constant term cto the right side of the equation: ax2+ bx =

    c.

  2. Divide both sides of the equation by the coefficient of x2( a): x2+ (b/a)x =

    c/a.

  3. Add the square of half the coefficient of xto both sides of the equation: x2+ (b/a)x + (b/2a) 2=

    c/a + (b/2a)2.

  4. Factor the left side of the equation as a perfect square trinomial: (x + b/2a)2=

    c/a + (b/2a)2.

  5. Take the square root of both sides of the equation: x + b/2a = ±√(-c/a + (b/2a)2) .
  6. Solve for xby isolating it on one side of the equation: x =

    b/2a ± √(-c/a + (b/2a)2) .

Completing the square can be used to solve any quadratic equation, regardless of its complexity.
