The expression u² - 6u rewritten by completing the square is (u - 3)² - 9

How to rewrite the expression by completing the square

From the question, we have the following parameters that can be used in our computation:

u² - 6u

Take the coefficient of u

k = -6

Divide this coefficient by 2

k/2 = -3

Square this result

(k/2)² = 9

This means that the number to add 9 - 9 to the expression u² - 6u

So, we have

u² - 6u + 9 - 9

Group the first three terms

(u² - 6u + 9) - 9

Factorize this terms

(u - 3)² - 9

Hence, the expression rewritten by completing the square is (u - 3)² - 9
