Question

Couple questions for Algebra 1 and up!!

Answer 1

A couple of questions i like the sound of that hahahah

Answer 2

\[6n^{-3}y/2n^{-1}y^{-3}\]

haha yeah ive done these before but icant remember exactly...

Answer 3

oh, im suppoed to simplify that

Answer 4

oh gawd i hate those

Answer 5

To start - write it as a fraction like it should be. Then realize negative exponents mean it's 1 over the exponent.

Answer 6

just subtract your bottom exponents from your top exponents; then sort the madness

Answer 7

I did write it as a fraction, i couldnt find the button for that now. Like i said, my teacher was out today and over the year we did the charpters out of order... like 123456789 12 11 10, and my teacher was out so a sub gave us the wrong thing or something

Answer 8

get the reciprocal to remove the negatives because no polynomial can have a negative exponent. then simplify.

Answer 9

amistre i have no clue what u are talking about :/

Answer 10

the button is: type in, frac{}{} into the eq editor

Answer 11

subtraction; its the opposite of addition :/

Answer 12

\[\frac{n^{top}}{n^{bottom}}=n^{(top-bottom)}\]

Answer 13

\[\frac{6n^{-3}y}{2n^{-1}y{-3}}\]

Answer 14

thats y^{-3}

Answer 15

so, the number part is just a normal fraction 6/2

the rest is n^(-3--1) y^(1--3)

Answer 16

i know subtraction is the opposite of addition!!! i didnt know if you took away the bottom N when it simplified 6n/2n.:( i went to kindergarten :(

Answer 17

:) just subtract the bottom stuff from the top stuff (exponentwise); after you simplfy see if you still got negative exponents; if so, drop them under the bar

Answer 18

Let's start here:
\[\frac{6n^{−3}y}{2n^{−1}y^{−3}}\]
Personally I like writing negative exponents as a reciprocal first. The effect is moving it from bottom to top or top to bottom:
\[\frac{6yn^{1}y^{3}}{2n^{3}}\]

Then simplify:
\[\frac{6n^{1}y^{4}}{2n^{3}}\]
And subtract exponents as they are being divided
\[\frac{3y^{4}}{n^{2}}\]

Answer 19

Thank you! and i have another one... what is the degree of the polynomial mean?

Answer 20

\[\frac{6n^{−3}y}{2n^{−1}y^{−3}}=3n^{(-3--1)}y^{(1--3)}\to\ 3n^{-2}y^4=\frac{3y^4}{n^2}{}\]

Answer 21

the degree of a poly is the highest exponential count of a single term

Answer 22

4xyz = degree 3

x^2 y^5 = degree 7

etc ..

Answer 23

but only variables count for some reason

Answer 24

And of course, terms are separated by + or -:

\(4x^2y^5+4j^6-3x^2+5\)

Can you find the degree of this polynomial?

Answer 25

single term as in \[2x^{3}y\] not \[2x^{3}y-4xy^{2}+9x^{3}y^{2}\]

Answer 26

right? and the degree is 7

Answer 27

Right and right.

Answer 28

so the degre of the one i posted is.. 5?

Answer 29

Yep, on the last term.

Answer 30

cool! one more, if you can?
Which binomial is a factor of \[6x ^{2}+x+12\]?
3x-3,3x-4, 6x+3, or x+4

Answer 31

What do you wish to find?

Answer 32

Idk the question is Which binomail is a facot of that thing that i posted up ther^

Answer 33

You'll have to use the quadratic formula to factor this, unless you mean 6x^2+xMINUS 12, which I think you do.

Answer 34

i do yteah, soorry

Answer 35

Factor by decomposition. Find two numbers that multiply to 6*12 and add up to the coefficient of x, 1.

Answer 36

when i factored it, i got (3x+4)(2x-3). thats not any of theanswers

Answer 37

\[6x^2+x-12\]
\[6x^2+9x-8x-12\]
\[3x(2x+3)-4(2x+3)\]
\[(3x-4)(2x+3)\]

Answer 38

yeah i saw what i did wrong
thanks ! :)
