Question: Wich is the origin of epixiban and rivaroxaban, direct factor X inhibitors? How were they discovered? Wich is the origin of epixiban and rivaroxaban, direct factor X inhibitors?
They come from leeches?
Answer: The drug you're referring to is actually Apixaban. It is very new and the research is limited. http://www.ncbi.nlm.nih.gov/pubmed/17868â€¦
Rivaroxaban: http://en.wikipedia.org/wiki/Rivaroxaban
This neatly explains the somewhat loose relationship between leeches and the modern medications you've mentioned:

Question: How do i completely factor x^61 over the complex/imaginary numbers? How do I factor x^(6)1 completely over the complex numbers.
It can be factored down to (x^31)(x^3+1) but then what? I can't use the quadratic equation since its cubic.
Answer: There are also formulas for the sum or difference of cubes:
aÂ³ + bÂ³ = (a + b)(aÂ²  ab + bÂ²)
aÂ³  bÂ³ = (a  b)(aÂ² + ab + bÂ²)
So
xÂ³  1 = (x  1)(xÂ² + x + 1)
Using the quadratic equation on the second term,
x = [1 Â± âˆš(1  (4)(1)(1))]/2
Â = Â½ Â± (âˆš3 / 2)i
So
xÂ³  1 = (x  1)(x (Â½ + (âˆš3 / 2)i)(x (Â½  (âˆš3 / 2)i)
Â = (x  1)(x + Â½  (âˆš3 / 2)i)(x + Â½ + (âˆš3 / 2)i)
I'll let you deal with the other cubic term.
Question: How would factor (x^(3/2)8)/(x4) to remove a discontinuity in calculus? Hi, With x approaching 4, I get 0/0 so I know theres a removable discontanuity, how do I factor this to remove it?
Answer: Define the function as follows:
f(x) = (x^(3/2)8)/(x4), xâ‰ 4
f(x) = 3 , x=4
The function will be continuous.
Question: How do you factor x^2+9 in the complex number system? I have a question that states x^2+9 cannot be factored in the real number system but it can be in the complex. How is this done? Thanks!
Answer: The best way to look at this is by proceeding as you normally would, by solving the equation x^2+9=0 for x. This gives you x^2=9, so x is equal to the square root of 9. This is obviously not a real number! However, Sqrt(9)=Sqrt(1*9)
=Sqrt(1)*Sqrt(9). Sqrt(1) is defined by the symbol i, and so your solutions for x are 3i and 3i. Thus, you can factor x^2+9 as (x+3i)(x3i).
Question: How does one factor x squared + 8x +18 in complex number system? I know how to do the quadratic formula, but that just solves for x it doesn't show me the imaginary factors.
Answer: x^2 + 8x + 18
using quadratic formula
x = [8 +/ sqrt(64  72)]/2
=> [ 8 +/ sqrt(8)]/2
=> [ 8 +/ sqrt(8 i)]/2, where i = sqrt(1)
=> 8 +/ 2 sqrt(2i)/2
=>4 +/ sqrt(2i)
Question: How do you factor x^2x20 using the ac method? Also how do you factor 9x^2+6z+1 also using the ac method?
this is what I got for the 1st problem:
x^2x20
x+4x5x20
(x+4x)(5x20)
x(1+4)5(x+4)
This is what I got for the 2nd problem:
9x^2+6x+1
9x+3x+3x+1
3x(3+1)+1(3x+1)
What did I do wrong for both of these?
Answer: x^2  x  20 (find two integers that multiply to equal 20, but add to equal 1, which are 4 and 5)
x^2 + 4x  5x  20 (group into pairs; because the first term of the second pairing has a negative in front of it, put a plus in between the parentheses)
(x^2 + 4x) + (5x  20) (factor out greatest common factor of each group)
x(x + 4)  5(x + 4) (factor)
(x  5)(x + 4) <===ANSWER
9x^2 + 6x + 1 (find two integers that multiply to equal 9, but add to equal 6, which are 3 and 3)
9x^2 + 3x + 3x + 1 (group into pairs)
(9x^2 + 3x) + (3x + 1) (factor out greatest common factor of each group)
3x(3x + 1) + 1(3x + 1) (factor)
(3x + 1)(3x + 1)
(3x + 1)^2 <===ANSWER
Question: When is the X factor boot camp going to start? The X factor is so boring this year. How many more weeks is it to the stage that they decide who is going to the judges house?
Answer: When the auditions are finished. I don't know how long that will be.
Question: How do the x factor contestants pay for things? They live in the x factor house but how do they get food etc? Do they get like an allowance or something?
Answer: Yeah they get an allowance, big brother contestants get a weekly payment thing too to cover their rent while they are in the house and unable to work.
