Learn how to find the value c that completes the square with a fraction, x^2 + 5x + c

The video tutorial explains the process of taking B/2 and squaring it, emphasizing the importance of keeping it as a fraction rather than converting to a decimal. The teacher encourages students to practice this skill in preparation for the next class, where more detailed explanations will be provided. An example calculation of 5/2 squared is demonstrated, resulting in 25/4. The tutorial concludes with an explanation of writing the expression in factored form as (X + 5/2)^2.
