Question

Not sure how to solve this.

f(x) x^2+12x+27
g(x)=x+9
(f/g)(x)

Answer 1

you have to solve this (x² + 12x +27)/(x+9), you can use many methods, briot ruffini and others

Answer 2

okay

Answer 3

i still don't know how to solve this

Answer 4

\[(f/g)(x) = \frac{f(x)}{g(x)} = \frac{x^{2} + 12x + 27}{x + 9}\]

Answer 5

Try factoring x^2+12x+27. If you get x+9 as one factor,then the other factor is the solution.

Answer 6

i understand how to set it up but i ended up witht he wrong answer (x+2)

Answer 7

Alright. First, factor \(x^{2} + 12x + 27\).Can you do that?

Answer 8

no

Answer 9

Find factors of 27 that add to 12. Then place the factors where I signify them:
\[x^{2} + 12x + 27 = (x + \space factor1)(x + \space factor2)\]

Answer 10

(x+3)(x+9)

Answer 11

\[\small(f/g)(x) = \frac{f(x)}{g(x)} = \frac{x^{2} + 12x + 27}{x + 9} = \frac{(x + 9)(x + 3)}{x + 9} = \frac{\cancel{(x + 9)}(x + 3)}{\cancel{x + 9}} = x + 3\]

Answer 12

i get it. thanks!

Answer 13

np :)

Answer 14

can you help me with another problem?

Answer 15

Do you have it posted?

Answer 16

f(x)=2x^2-4x+6 and g(x)=x-1; (f x g)(x)

Answer 17

Just do:
(x - 1)(2x^2 - 4x + 6) = ?

Answer 18

2x^3-2x^2+10x+6

Answer 19

Close. It's \(2x^{3} - 6x^{2} + 10x - 6\)

Answer 20

those signs get me! could you help me figure out what i did on wrong on one more question?

Answer 21

Alright. By your wording, I'm guessing you have an answer and you want me to check it?
