Figure out the equation for each of the multiple choice.

Answer:

B

Step-by-step explanation:

Given

y = x² - 10x + 9

Using the method of completing the square

add/subtract (half the coefficient of the x- term)² to x² - 10x

y = x² + 2(- 5)x + (- 5)² - (- 5)² + 9

 = (x - 5)² - 25 + 9

 = (x - 5)² - 16 → B
