How To Complete The Square

To complete the square, first, you want to get the constant (c) on one side of the equation, and the variable(s) on the other side. To do this, you will subtract 8 from both sides to get 3x^2-6x=15. Next, you want to get rid of the coefficient before x^2 (a) because it won´t always be a perfect square. Step 1: Write the quadratic equation as x 2 + bx + c. ( Coefficient of x 2 needs to be 1. If not, take it as the common factor.) Step 2: Determine half of the coefficient of x. Step 3: Take the square of the number obtained in step 1.

How To Complete The SquareThis method is known as completing the square method. We have achieved it geometrically. We know that, x2 + bx + c = 0. This can be written as: (x + b/2)2 + (c – b2/4) = 0. ⇒ (x + b/2)2 = - (c – b2/4) This formula can be used to solve the quadratic equations by completing the square technique. Step 1 Write down the equation Let s say you re working with the following equation 3x2 4x 5 Step 2 Factor out the coefficient of the squared term from the first 2 terms To factor out a three from the first two terms simply pull out a 3 and place it around a set of parenthesis around both terms while dividing each term by 3 3x2

What is completing the square? Completing the square is a technique for rewriting quadratics in the form ( x + a) 2 + b . For example, x 2 + 2 x + 3 can be rewritten as ( x + 1) 2 + 2 . The two expressions are totally equivalent, but the second one is nicer to work with in some situations. Example 1 F t Completing The Square
