That link isn't going to work without giving out a username and password, so I suggest prt sc and copying/pasting to paint or similar so that we may view it.

anonymous · Answer

$$\frac{ 2x }{ x ^{2}-6x+9 }+\frac{ 4 }{ x ^{2} +2x-15}$$

mathmale · Answer

What are the instructions for this problem?

anonymous · Answer

Find the sum

mathmale · Answer

Please factor each of the two denominators, so that we can identify and use the Lowest Common Denominator (LCD).

anonymous · Answer

2(x3+4x2−15x+6)(x2+3)(x+5)(x−3)

mathmale · Answer

I don't see how you got x3 (by which you mean "the cube of x," or x^3).

Given:$$\frac{ 2x }{ x ^{2}-6x+9 }$$

mathmale · Answer

please focus on the denominator (only).  Factor the denominator (separate it into two binomial factors).

mathmale · Answer

similarly, factor the denominator of the second rational function.

anonymous · Answer

i dont know

mathmale · Answer

Morris, have you any experience factoring trinomials?  I'd bet you have.  

x^2 - 6x + 9 is called a "trinomial," because it has 3 terms.

a + b is a "binomial," because it has 2 terms.

I am asking you to factor the trinomial x^2 - 6x + 9 into its two binomial factors:

x^2 - 6x + 9 = (        )(        )

mathmale · Answer

Hint:  x^2 - 6x + 9 is a perfect square.  What does that mean to you?
