Factor the polynomial x2 - 10x + 25. write each factor as a polynomial in descending order.

(x-5)²

Step-by-step explanation:

To factor this

x² - 10x + 25.

We are going to look for two numbers such that its sum is equal to -10 and its product is equal to 25

The two numbers are -5 and -5

The sum of -5 and -5 is -10

and the product of -5 and -5 is 25

We will then replace -10x by  -5x-5x

x² - 5x -5x + 25

(x² - 5x )(-5x + 25)

We can now go ahead and factorize

x (x-5) - 5(x-5)

=(x - 5)(x-5)

=(x-5)²

answer: 1, 3 and 5 are correct

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
