Question

x^7+x^6
--------
x

I think the answer is 1^7+ 1^6.... am I right??

Answer 1

\[\frac{x^7+x^6}{x}\]
can you factor out an x from both pieces on top?
\[\frac{(x)x^6+(x)x^5}{x}\to \frac{(x)(x^6+x^5)}{x}\]

Answer 2

so I'm supposed to multiply the two x's could you walk me through it...I have an example with numbers which I found very easy but the letters have me thrown off

Answer 3

No this lets you do the division easier.

\[\frac{(x)(x^6+x^5)}{x}\to \left(\frac{x}{x}\right)\frac{x^6+x^5}{1}\]
you know what (x/x) is?

Answer 4

I thought x/x=1

Answer 5

Yes. so it cancels and what are you left with?

Answer 6

0

Answer 7

please forgive me if im wrong I'm completely illiterate when it comes to math

Answer 8

you are left with
\[x^6+x^5; x\neq 0\]

Answer 9

ok I think I understand that, if I can make my brain understand numbers with letters this may become easy for me...thanks

Answer 10

Keep trying:) variables are more general.

Answer 11

btw can you tell me what the line through the equal sign means...I know it's not equal to but is that all of it?

Answer 12

yes. its basically a short hand way of saying that x can't be zero since in the original equation you are dividing by x. And you cannot divide by 0

Answer 13

okay thanx again!!!
