Question

Please Help me.. :)

(2/x^28x+15) +(1/x^2+11x+30)

Answer 1

Factor the denominators and then find the LCD.

Answer 2

They don't have a LCD because some of the numbers are prime.

Answer 3

none of them is prime

Answer 4

You said i should find the LCD but 11x is only divisible by it self.

Answer 5

\[\frac{2}{(x+3)(x+5)} + \frac{1}{(x+5)(x+6)}\]Can you solve now?

Answer 6

I can try. Okay.

Answer 7

I took the function you gave me and i took the 2 and divided it into the six leaving them to be the same. So do i go ahead and add them straight across

Answer 8

o_O

Answer 9

Is that correct? I got 2/(x+5) (x+3)

Answer 10

no

Answer 11

2/(x+10) (x+9)

Answer 12

Nope

Answer 13

What am i doing wrong?

Answer 14

The function you gave me should i have just continued to add straight across?

Answer 15

Yes, but u have to take the LCD first

Answer 16

Is the LCD is (x+5)

Answer 17

(x+5)(x+3)(x+6)

Answer 18

3/(x+5)(x+3)(x+6)

Answer 19

\[\frac{2(x+6) + 1(x+3)}{(x+5)(x+3)(x+6)}\]

Answer 20

Now do i cancel them or multiply?

Answer 21

Just simplify.

Answer 22

I got two different answer: The first one i cancel them out i got 3/(x+5)
The second answer i multiplied straight across then cancel out (x+2)/(x+5)
Is any of them correct?

Answer 23

none

Answer 24

\[\frac{2x+12+ x + 3}{(x+5)(x+3)(x+6)}\]
\[\frac{3x+15}{(x+5)(x+3)(x+6)}\]
\[\frac{3(x+5)}{(x+5)(x+3)(x+6)}\]

Answer 25

\[\frac{3}{(x+3)(x+6)}\]

Answer 26

I saw how you got it but that's what i got too.

Answer 27

Thank you for all your help. I really appreciated it.

Answer 28
