How To Solve Equation Using Completing The Square Method

How To Solve Equation Using Completing The Square Method - 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. Algebra Examples Step by Step Examples Algebra Quadratic Equations Solve by Completing the Square x2 8x 1 0 x 2 8 x 1 0 Add 1 1 to both sides of the equation x2 8x 1 x 2 8 x 1 To create a trinomial square on the left side of the equation find a value that is equal to the square of half of b b

We can complete the square to solve a Quadratic Equation (find where it is equal to zero). But a general Quadratic Equation may have a coefficient of a in front of x2: ax 2 + bx + c = 0 To deal with that we divide the whole equation by "a" first, then carry on: x 2 + (b/a)x + c/a = 0 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.
