Question

Can someone help me with this?
x -2 x^2+3x -10

Answer 1

what do you want to do with it?

Answer 2

Simplify the rational expressions. State any excluded values. Show your work.

Answer 3

that's a polynomial expression. A rational expression is a fraction

Answer 4

Okay.

Answer 5

Other then that, that's all i have for information

Answer 6

is that the exact way it's written? there's no numerator/denominator?

Answer 7

2x/x^2+3x-10 sorry didn't include the division.

Answer 8

like this?
\[\frac{ 2x }{ x^2+3x-10 }\]

Answer 9

Yes like that

Answer 10

Usually you'd factor like this and something will cancel from the numerator and denominator.
\[\frac{ 2x }{ (x+5)(x-2) }\]

Since nothing canceled, the original is already simplified.

For excluded values set the denominator equal to 0.
\[(x + 5)(x - 2) = 0\]
So you need to solve
\(x+5=0\) and
\(x-2=0\)

Answer 11

Alright. x+5-5=0-5 x= -5
X-2+2=0+2 = 2

Answer 12

yes, so -5 and 2 are the excluded values

Answer 13

Okay.

Answer 14

So i'm finish @peachpi?

Answer 15

yeah, unless they asked for something else

Answer 16

Alright thanks :) bye.
