Answer:

(x² - 8x + 16) = (x-4) (x-4)

Step-by-step explanation:

We have to factorize the given expression

(x²-8x+16)

(x² - 8x + 16 ) = x² - 2(4x) + 4²

                    = ( x-4)²

[As we know (a-b)² = a² + b² - 2ab]

so (x² - 8x + 16) = (x-4) (x-4) is the factored form of the given expression.
