What value is needed to complete the square? Show all steps.
x² - 6x+ __

9

Step-by-Step-Explaination

(x+3)^2 + x^2 + 3^2 so we already have x^2, so we have 9, 3^2, left.

9

Step-by-step explanation:

To complete the square

add ( half the coefficient of the x- term )² to x² - 6x

x² + 2(- 3)x + (- 3)²

= x² - 6x + 9

1 is b and 2 is d

step-by-step explanation:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
