The calculator solution will show work to solve a quadratic equation by completing the square to solve the entered equation for real and complex roots.
To do that a perfect way would be to represent the terms of expression in the LHS of an equation. For example x²6x5 isnt a perfect square but if we add 4 we get x3². This in essence is the method of completing the square. Solve equation 3x 2 2x - 5 0.
