There is one extra step for solving this equation because the leading coefficient is not 1. For example x²6x5 isnt a perfect square but if we add 4 we get x3². Lets start with the solution and then review it more closely.
2 x2 5 x 1 0.
Next to get x by itself add 3 to both sides as follows. Now continue to solve this quadratic equation by completing the square method. ----- To see many other similar solved problems look into the lesson - HOW TO solve quadratic equation by completing the square - Learning by examples in this site.
