 $\frac{x^2-x-6}{x-3}\cdot\frac{x+9}{x+2}$  

•  $x+9$  
  

•  $\frac{x-3}{x-2}$  

•  $\frac{x+9}{x+2}$  

•  $x-3$  

Simplify the expression

• (19k² -12k - 12) / 4k(5k-4)
• (19k² - 24k) / 4k(5k-4)
• (19k) /  4(5k-4)
• (19k - 24) / 4(5k-4)

Subtract the following rational expression.

• (28x-29)  /  5(7x+6)
• (28x-11)  /  5(7x+6)
• (7x-11)  /  5(7x+6)
• (7x-29)  /  5(7x+6)

 $\frac{7x-49}{x^2+8x+12}=\frac{3}{x+6}+\frac{1}{x+2}$  

•  $-2$  

•  $5$  

•  $6$  

•  $\frac{61}{3}$
