How do I determine the number of time 2 is a root of:

x^6 - 9x^4 +24x - 16 = 0

I know to use synthetic division but how do I know how many times to divide it??

my boyfriend and i were arguing about this (not really arguing about it, but more like debating.) and he claims that black is a color simply because when asked "what color are your sunglasses?" one would reply "black." And no one ever says "well actually, it is the absance of color."However, i believe that it is not a color due becuase black absorbs all colors. Nothing is reflected back into your eye. So technically you cant even SEE black...its just empty space. Also, black is NOT on the color wheel. Furthermore, when you close your eyes, you are blocking all color from entering your eye, and you see black. So...is black a color?

I am not looking for exact answers just guidance on what to do and would greatly appreciate it:)

I have 2 equations that say Solve For X, but I can't figure out what I need to do

10^x=384
e^x=116

I don't know if we exactly learned how to do those yet...

Another problem says Determine the Value of x & Y if 2^y=8^x and 3^y=3^x+4


Thanks for helping!

can a neutron exist without protrons and electrons?
would it have any use?

A cross between two pea plants with axial flowers and inflated pods gives the following offspring: 20 with axial flowers and inflated pods, 7 with axial flowers and constricted pods, and 5 with terminal flowers and inflated pods. What is the most probable genotype for the two parents? Explain the results and show the Punnett square. How can the explanation be checked?

Please tell me how to do this and work it out so I know how!

THANKS!!!!!

Algebra Help
Hey everyone! I have a hw question in algebra.
1. A comany makes backpacks. How many backpacks must the company sell to make a profit of more than $250?

Profit:
nylon pack=$3
canvas pack=$10

*My math text book says "10 nylon packs and 22 canvas packs" is not a solution. Why isn't a solution because that's the answer I got?

Thanks.
