Answer: -3x^3 - 7x^2 - x + 39

Step-by-step explanation:

2/(x^2 -9) - 3x/(x^2-5x+6)

get those denominators factored out

2/(x-3)(x+3) - 3x/(x-3)(x-2)

Multiply both by both denominators

2(x-3)(x-2) - 3x(x-3)(x+3)

Multiply it out

(2x^2 - 10x + 12) - (3x^3 + 9x^2 -9x - 27)

Simplify and it becomes

-3x^3 -7x^2 -x + 39

Complete Question

The complete question is shown on the first and second uploaded image

Answer:

$\= HK = \= t + \= u$

$\= GL = \= s - \= t$

$\= JH = \= u + \= s$

Step-by-step explanation:

Now looking at the diagram

Following the direction of the unit vectors $\= u , \= s, \= t$

$\= {HK} = \= {KI} + \= KL$

=> $\= HK = \= t + \= u$

And

$\= GL = \= GH + \= GF$ jjj

=> $\= GL = \= s - \= t$

Also

$\= JH = \= JG + \= JI$

=> $\= JH = \= u + \= s$
