Question

Adiya said that the first step to solving the quadratic equation x2 + 6 = 20x by completing the square was to divide 6 by 2, square that value, and add the result to both sides. Is Adiya’s solution method correct? Explain

Answer 1

Answer:

No.

Step-by-step explanation:

In order to complete the square, you need to have the x values together, not the constant.

To complete the square correctly you would need to have x² - 20x = -6 and continue from there; divide 20 by 2 and square the result to get (x - 10)² = 96.
