Question

Simplify Please:
x^3+8x^2+20x+13/(x+3)(x-2)

Answer 1

It didn't simplify it completely :/

Answer 2

It's all good

Answer 3

Did you figure it out though, @itsallycatt?

Answer 4

No I didn't...

Answer 5

So your problem follows the "sum of cubes" formula, in that \[(a^3+b^3)= (a+b)(a^2-ab+b^2)\]

Answer 6

@jim_thompson5910 over here

Answer 7

Are you sure that is the equation? I don't see any way in which it can be simplified substantially. Then again I might just be missing something.

Answer 8

ohhhh i figured it out, i think haha

Answer 9

That's what I thought... The answer choices are
1/(x+3)(x+4)
1/(x+3)(x-2)
1/(x+4)(x-2)
1/(x+3)(x+1)

Answer 10

multiply (x+3)(x-2) to get a quadratic equation and then use long division to simplify

Answer 11

I'm assuming all of x^3+8x^2+20x+13 is over (x+3)(x-2)

If so, then you can expand out (x+3)(x-2) to get x^2+x-6

then you can use polynomial long division to get the quotient for (x^3+8x^2+20x+13)/(x^2 + x - 6)

Answer 12

xD yay jim! haha

Answer 13

(x+3)(x-2) = x^2 + x - 6

and

x^3+8x^2+20x+13/ x^2 + x - 6

= (x+7) (x^2 + x - 6) with a remainder of (19x +55)

Answer 14

something seems missing though because none of the answer choices will match the quotient or the remainder

so is there more to the problem?

Answer 15

I have no ideaa, that was the problem I was having...

Answer 16

@Jack1 how did you get your (x+7)(x^2 +x - 6)....

Answer 17

none of these match up... do they have brackets around any of the initial question on the top line?
1/(x+3)(x+4)
1/(x+3)(x-2)
1/(x+4)(x-2)
1/(x+3)(x+1)

Answer 18

@Jhannybean long division

Answer 19

No they don't...

Answer 20

Ohhh. nevermind. Gotcha.

Answer 21

(x^2 + x - 6) times x = x^3 +x^2 -6x
goes into x^3+8x^2+20x

..cool nvmd

Answer 22

xD yeah this problem is kicking my booty.

Answer 23

@Jhannybean dont feel bad, its not the answerer, its the question, the fact that there's a remainder means that it doesn't simplify into one of the optional answers, so something in the q's wrong, maybe the people who wrote it put a sign wrong... dunno
