1. Start with a quadratic equation set = 0.


2. Move the constant to the right side. 

3. Divide each term by a to get the leading coefficient to be one. 

4. Get ready for a perfect square trinomial on the left side (put in the boxes). 

5. To find the needed value, take half of the coefficient of the xterm, , and square it, . Add this value to both sides of the equation (put it in the boxes). 

6. Square the last term on the right side. Find a common denominator on the right. 

7. Combine terms on the right, placing b^{2} in front of 4ac in the numerator. 

8. Rewrite the perfect square trinomial on the left side as the square of a binomial. 

9. Take the square root of both sides. Simplify the radical on the right side. 

10. Subtract the constant away from x. Write as a single fraction on the right side.
