Completing the square (Algebra 1, Quadratic equations) – Mathplanet.

Completing the square is a technique for rewriting quadratics in the form ( x + a ) 2 + b (x+a)^2+b (x+a)2+bleft parenthesis, x, plus, a, right parenthesis, squared, plus, b.

What is the Rule for Standard Form? Standard form for linear equation in two variables x and y is given as Ax + By = C, where A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.

Study summary Move the constant to the right side of the equation. Divide both sides by the constant. To complete the square, add or subtract the same value to both sides. Factor the expression on the left side of the equation. Calculate the sum or difference on the right side of the equation. Solve the equation.

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, x²+6x+5 isn't a perfect square, but if we add 4 we get (x+3)². This, in essence, is the method of *completing the square*.

List of All Algebra Formulas for Class 9 ( a + b)2 = a2 + 2ab + b2 ( a − b)2 = a2 − 2ab + b2 ( a + b)(a – b) = a2 – b2 ( x + a)(x + b) = x2 + (a + b)x + ab. ( x + a)(x – b) = x2 + (a – b)x – ab. ( x – a)(x + b) = x2 + (b – a)x – ab. ( x–a)(x–b) = x2 – (a+b)x + ab. ( a + b)3 = a3 + b3 + 3ab(a + b)

Completing the Square is a technique which can be used to find maximum or minimum values of quadratic functions. We can also use this technique to change or simplify the form of algebraic expressions. We can use it for solving quadratic equations.
