Note: Completing the square formula is used to derive the quadratic formula. Completing the square formula is a technique or method that can also be used to find the roots of the given quadratic equations, ax 2 + bx + c = 0, where a, b and
To complete the square, the leading coefficient, a a , must equal 1. If it does not, then divide the entire equation by a a. Then, we can use the following procedures to solve a quadratic

Some quadratic expressions can be factored as perfect squares. For example, x²+6x+9= (x+3)². However, even if an expression isn't a perfect square, we can turn it into one by adding a constant number. For example
The completing the square formula is given by, ax 2 + bx + c ⇒ a(x + m) 2 + n. Where, m = b/2a, n = c – (b 2 /4a) Here, m can be any real number and n is a constant.
The general form of a quadratic equation looks like this: ax 2 + bx + c = 0 Completing The Square Steps Isolate the number or variable c to the right side of the equation. Divide all terms by a (the coefficient of x2, unless x2 has no
