<h3>Answer:   B)  -6</h3>

Using the box method or FOIL rule, you should find that (x-3)^2 = x^2-6x+9

An alternative is to use the perfect square formula (a-b)^2 = a^2 - 2ab + b^2 where in this case a = x and b = 3.

Answer:

- 6

Step-by-step explanation:

Given

(x - 3)² = (x - 3)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 3) - 3(x - 3) ← distribute both parenthesis

= x² - 3x - 3x + 9 ← collect like terms

= x² - 6x + 9

The coefficient of the x- term is - 6
