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.

What is the first step in the process of completing the square as described in the video?

• Subtract 2 from B

• Add 2 to B

• Divide B by 2

• Multiply B by 2

Why does the teacher emphasize leaving the result as a fraction?

• Because 2 does not evenly divide into 5

• Because decimals are not allowed in this exercise

• Because fractions are more accurate

• Because fractions are easier to calculate

What is the main purpose of practicing the B/2 squaring technique according to the teacher?

• To memorize the formula

• To improve calculation speed

• To understand the concept better in the next class

• To prepare for a test

What is the result of squaring 5/2 as shown in the video?

• 10/4

• 15/4

• 25/4

• 20/4

How is the expression X^2 + 5X + 25/4 written in factored form?

• (X + 2/5)^2

• (X + 5/2)^2

• (X + 5)^2

• (X + 1/2)^2
