Factor the expression below. x2 - 6x + 9 A. 3(x2 - 2x + 3) B. (x - 3)(x + 3) C. (x + 3)(x + 3) D. (x - 3)(x - 3)
2 answers:
For this case we must factor the following quadratic expression:

To factor, we must find two numbers that when multiplied give as result +9 and when added or subtracted give as result -6.
These numbers are:
-3 and -3

So, we have:

ANswer:
Option D
<u>Answer:</u>
D. (x - 3)(x - 3)
<u>Step-by-step explanation:</u>
We are given the following expression and we are to factorize it:

Finding factors of positive 9 such that when added they give a result of -6.


Factorizing them to get:

Everyday the number is tripled by 3 and x represents the number of days, which we don’t know, so it would be 3x.
He started with 24.
So the equation is:
24+(3x)
I'm guessing the series is

Use the ratio test: we have

The series converges for

which has a radius of convergence of 1.
