On this example which expression am I dividing and with which expression am I doing the division ?

Answer 1

@e.mccormick

Answer 2

Yeah, that's right

Answer 3

Then you're left with:
\[3 + \frac{ -12x-22 }{ x ^{2}-4x+4 }\]
But I didn't see the "-22" term initially -- guess you will have to do partial fractions...

Answer 4

Do you know how to set that up?

Answer 5

whoops, that first "-12x" term should be "12x" (not negative)

Answer 6

I don't know who's the quotient and who's the divisor

Answer 7

who's dividing what ? I need to understand the terms

Answer 8

The quotient is the result. The divisor is in the denominator. And the "dividend" is in the numerator.

Answer 9

and who's dividing the divided ?

Answer 10

The divisor divides the dividend. #tonguetwister

Answer 11

Answer 12

@dan815

Answer 13

Am I not helpful enough... sad

Answer 14

Anyway, it should end up to be something like:

\[3 + \frac{ 12 }{ x-2 }+ \frac{ 2 }{ (x-2)^{2} }\]
And then just integrate that...

Answer 15

But I didn't ask that did I ? I asked what's the number that is dividing the denominator

Answer 16

lol

Answer 17

If understand the terms then I can get results myself

Answer 18

I just have to learn what is doing what , then I can do the process again and again

Answer 19

You mean the expression in the denominator--that's called the "divisor".

Answer 20

\(x^2 - 4x + 4\) is the divisor.

\(3x^2 - 10\) is the dividend

The quotient is the end result of dividing.

Answer 21

thank you

Answer 22

That's exactly what I said earlier!!

Answer 23

Sorry man I may have confused it then

Answer 24

anyway thanks for helping
