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.
To round you must see if the fraction is greater or less than a half to see if you round up or down. 1/8 is less than 1/2, so you must round down. So the answer is 5.
