For this case we must factor the following quadratic expression:

x ^ 2-6x + 9

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

-3-3 = -6\\-3 * (- 3) = + 9

So, we have:

(x-3) (x-3)

<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:

x^2-6x+9

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

x ^ 2 - 6 x + 9

x ^ 2 - 3 x - 3 x + 9

Factorizing them to get:

x ( x - 3 ) - 3 ( x - 3 )

( x - 3 ) ( x - 3 )

Jake is observing the population growth of insects. He started with 24 insects and the population triples every day.
Artemon [7]
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)

Find the radius of convergence, R, of the series. ∞ (−1)n (x − 6)n 4n + 1 n = 0 R =
Rina8888 [55]

I'm guessing the series is

\displaystyle\sum_{n=0}^\infty\frac{(-1)^n(x-6)^n}{4n+1}

Use the ratio test: we have

\displaystyle\lim_{n\to\infty}\left|\frac{\frac{(-1)^{n+1}(x-6)^{n+1}}{4n+5}}{\frac{(-1)^n(x-6)^n}{4n+1}}\right|=|x-6|\lim_{n\to\infty}\left|\frac{4n+1}{4n+5}\right|=|x-6|

The series converges for

|x-6|

which has a radius of convergence of 1.
