Question 205590: The question is: Classify the following polynomial by its degree and terms. x^2-5x+2. This is a multiple choice question. The choices are: quadratic binomial, cubic trinomial, quadratic trinomial, and linear binomial. So far what I have done is cancel out quadratic binomial and linear binomial because the equation has 3 terms(trinomial) and binomial stands for 2 terms. I don't know which one it is now , quadratic trinomial or cubic trinomial.

Question 206658: I have tried to figure this out for 2 days. I would really appreciate any help!!
Calculate the value of the fraction below and leave your answer in scientific notation.
(9.2x10^45)((?)x10^15)/1.2x10^-3
I think that it is the (?) that is giving me the problem.

Question 206758: okay, i don't think this is in the right spot but its the closest thing to my problem.
Directions: Write the fraction in simplest form. (read it down, cuz its on a slant)
1. 35k to the 2nd | 2. 64a to the 5th | 3. 51xy to the 3rd | 4. 24mp
-------------- | ---------------- | ------------- | --------
28k | 8a to the 3rd | 34x to the 4th |40m to the 2nd
p to the 3rd
I don't know where to start... or what to do, really. You don't have to help me with all of those, I just gave them all to give you an idea of what I was doing.
Thanks for your help,
Mo

Question 208335: Hello,
Is 0.5 cubed (or, to the power of 3) equal to 0.125? As in 0.5 x 0.5 x 0.5 = 0.125? If not, what is the correct answer, and how would I figure out similar problems on a regular calculator or another method?
Thank you!

Question 210965: Could someone tell me if these are right Thank you
Rewrite the following using only positive exponents.
3^-1 +1/3^1 = 1/3
(2.5)^-2 = 2^-2/5^-2 = 1/2 ^2 over 1/5^-2 = 1/2^2 . 5^2/1 = 5^2/2^ = 25/4
8 /8^-2 = 8^1/8^-2 = 8^1 + 8^3 = 512

Question 211128: How does one factor a polynomial where only two of items have negative exponents?
3x^-2 -7x^-1 -6 = 0
1/3x^2 - 1/7x - 6 = 0
Foil would give (1/3x - 3) (x + 2) - but how to get that - 1/7x in the middle (I can get - 7/3x)?

Question 211254: I am so confused by this.
Evaluate the exponential equation for three positive values of x, three negative values of x and x=0. Use the resulting ordered pairs to plot the graph. State the equation of the line asymptotic to the graph, if any.
y= -3^x
I think I would start with have y=f(x)=-3^
f(0)=-3^0=1
f(1)=-3^1=-3=1/3
f(2)=-3^2=9
f(3)=-3^3=-27=1/27
Before I go any further, am I on the right track?
