Gunnar Robertson · Answer 1

a²-2*a*b+b² = (a-b) ²

x²-6x+9=x²-2*x*3+3² = (x-3) ² C)

Anaya Pearson · Answer 2

C

Step-by-step explanation:

Given

x² - 6x + 9

Consider the factors of the constant term ( + 9) which sum to give the coefficient of the x - term ( - 6)

The factors are - 3 and - 3, since

- 3 * - 3 = + 9 and - 3 - 3 = - 6, thus

x² - 6x + 9 = (x - 3) (x - 3) = (x - 3) ² → C
