Question

simplify the following rational expression: x 2 -4x-5 x-5

Answer 1

can you clarify the expression, it is unclear

Answer 2

is it
\[\frac{x^2-4x-5}{x-5}\]?

Answer 3

factor and cancel
\[\frac{(x-5)(x+1)}{x-5}=\frac{\cancel{(x-5)}(x+1)}{\cancel{x-5}}=x+1\]

Answer 4

yes!

Answer 5

thanks god! someone finally figured it out!

Answer 6

method is clear right? factor if you can, then cancel the common factors

Answer 7

yep :) can u help me with another one?

Answer 8

yes

Answer 9

@katlin95 i helped u out, and i told u if what i was telling u was right relating to the equation was right and u would say, yes... but it was not :/

Answer 10

@katlin95 u sould but ur question a bit more clear

Answer 11

which expression represents 12 x 3 -6 x 2 +2x 2x in simplest form

Answer 12

are those times signs, or \(x\)'s

Answer 13

like the one above ^ its not clear. this usually happens when someone just copies and paste the question from online.

Answer 14

A. 6 x 2 -3x
B. 10 x 2 -4x
C. 6 x 2 -3x+1
D. 10 x 2 -4x+1

they are x's:)

Answer 15

@satellite73 ? where did u go?

Answer 16

is it like this
\[12 x^ 3 -6 x ^2 +2x\times 2x\]

Answer 17

yes

Answer 18

she kept telling me yes that i was correct also but at the end the equation i was talking about was nothing like how it was.

Answer 19

ok then
\[2x\times2x=4x^2\] so you have
\[12x^3-6x^2+4x^2=12x^2-2x^2\]

Answer 20

but that is not one of your choices, so i guess i read it wrong

Answer 21

maybe you could rewrite it, use ^ for exponents, like x^2 for x squared

Answer 22

@satellite73, no she is the one telling us the equation and writing it unclear

Answer 23

or else post the actual question as an attachment
