Formula for completing the square

To complete the square, first find the equation of the parabola. Next, divide each term in the equation by the coefficient of x2. Finally, add 1/4 to each term in the equation.

x2 + bx + c = 0

x2 + bx = -c

1/4 (x2 + bx) = -c/4

x2 + bx + (1/4) = -c/4 + (1/4)

x2 + bx + 1/2 = -c/4

x2 + bx + 1/4 = -c/2

Completing The Square Definition

Completing the square is a mathematical technique used to solve quadratic equations. The technique involves adding a constant to the equation so that the left side of the equation is a perfect square.

Example of completing the square based on Formula

The standard form of a quadratic equation is given by the formula:

ax2 + bx + c = 0

where a, b, and c are coefficients.

For example, if the coefficients are a = 1, b = 2, and c = 3, then the standard form of the equation is given by 1×2 + 2x + 3 = 0.

The equation can be rewritten in the form of (x + p)2 + q = 0 by completing the square. In this case, p = -b/(2a) and q = c – b2/(4a).

Therefore, the equation can be rewritten as (x + (-2/1))2 + (3 – 4) = 0, which is equivalent to (x – 2)2 – 1 = 0.
