Question

What is the formula for completing the square method?

Answer 1

Answer:

Compliting the square is the method use to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial.

Step-by-step explanation:

Ex:- ax2 + bx +c = 0

1. Transformer the equation so that the constant term, c is alone on the right side.

2. If a, leading coefficient (the coefficient of the x2 (x square) term), is not equal to 1, devide both side by a.

3.add the square of half the coefficient of the x- term(b/2a)2 to both side of the equation.

4. Factor the left side as the square of a binomial.

5. Take a square root of both sides.

Remember : (x+q) 2 = r is equivalent to

$x + q = \sqrt{r}$
