Rewrite the expression in factored form: x^2+12x+27
Answer choices:
A.(x-3) (x-9)
B.(x-3) (x+9)
C.(x+3) (x+9)
D.(x+3) (x-9)

c. (x+3)(x+9)

Step-by-step explanation:

x^2+12x+27

The middle number is 12 and the last number is 27.

We need two numbers that...

Add together to get 12

Multiply together to get 27

Try 3 and 9:

3+9 = 12

3*9 = 27

Fill in the blanks in

(x+_)(x+_)

with 3 and 9 to get...

(x+3)(x+9)

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
