Next to get x by itself add 3 to both sides as follows. A 1 a 2 so divide through by 2. In the quadratic equation x2 - 5x 6 0 the coefficient of x2 is 1.
In the given quadratic equation 4x 2 4bx - a 2 - b 2 0 divide the complete equation by 4 coefficient of x 2.
I If a does not equal 1 divide each side by a so that the coefficient of the x 2 is 1. Key Steps in Solving Quadratic Equation by Completing the Square. In the given quadratic equation 4x 2 4bx - a 2 - b 2 0 divide the complete equation by 4 coefficient of x 2. 5 3x 2 6x 7 0.
