Question

HELP PLEASE I DONT KNOW THIS ONE

Answer 1

Answer:

-3x^2 +7x -4

-------------------------------

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

Step-by-step explanation:

2              3x

--------   - ----------

X^2-9    x^2 -5x+6

Factor

2                 3x

--------   -      ----------

(x-3)(x+3)   (x-3)(x-2)

Get a common denominator

2  (x-2)               3x(x+3)

--------   -             ----------

(x-3)(x+3)(x-2)   (x-3)(x-2)(x+3)

2x-4  - (3x^2 -9x)

-------------------------------

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

Distribute

2x-4  - 3x^2 +9x

-------------------------------

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

Combine like terms

-3x^2 +7x -4

-------------------------------

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

Answer 2

$\boxed{\large{\bold{\textbf{\textsf{{\color{gold}{Answer \red{:)}}}}}}}}$

• $\sf{\dfrac{2}{ x^2-9}-\dfrac{3x}{x^2-5x+6}}$

• $\sf{\dfrac{2}{ (x)^2-(3)^2}-\dfrac{3x}{x^2-2x-3x+6} }$

• $\sf{\dfrac{2}{(x+3)(x-3)}-\dfrac{3x}{x(x+2)-3(x+2)} }$

• $\sf{\dfrac{2}{(x+3)(x-3)}-\dfrac{3x}{(x+2)(x-3)}}$

• $\sf{\dfrac{2(x-2)-3x(x+3)}{(x+3)(x-2)(x-3)} }$

• $\sf{\dfrac{2x-4-(3x^2-9x)}{(x+3)(x-2)(x-3) }}$

• $\sf{\dfrac{2x-4-3x^2+9x}{(x+3)(x-2)(x-3) }}$
