Answer:

<u>4</u>

Step-by-step explanation:

Given :

<u>f(x) = x² - 6x + 8</u>

<u />

=============================================================

Solving :

<u>Splitting the middle term</u> :

⇒ f(x) = x² - 6x + 8

⇒ f(x) = x² - 2x - 4x + 8

⇒ f(x) = x (x - 2) - 4 (x - 2)

⇒ f(x) = (x - 4)(x - 2)

============================================================

Solutions :

⇒ x - 4 = 0 ⇒ x = <u>4</u>

⇒ x - 2 = 0 ⇒ x = 2

A century year such as 1900, 2000, or 2100 is a leap year only if it is a multiple of 400
blondinia [14]
If this is a true or false question, then the answer is true. This is because we technically have 365.2425 days in a year and if you add an extra day every 4 years, you get an average of 365.25. It is A LOT of math, but even though there was an extra day in 1896 and 1904, there was no leap year in 1900 because of the 400 multiple rule.
