A x 2 b x c. After taking the square root of both sides you are left with x-3 - 5. Step 2 Move the number term ca to the right side of the equation.
In the given quadratic equation ax 2 bx c 0 divide the complete equation by a coefficient of x 2.
Divide both sides by the coefficient of x -squared unless of course its 1. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation. In this case weve got a 4 multiplied on the x2 so well need to divide through by 4 to get rid of this. X 8 and x -2.
