Answer 2

(x² + 11x + 6)/(x + 2)(x + 5) is equivalent expression for 2x/(x + 2)  - (x - 3)/(x + 5)

Step-by-step explanation:

2x/(x + 2)  - (x - 3)/(x + 5)

= {2x(x + 5) - (x - 3)(x + 2) }/(x + 2)(x + 5)

= { 2x² + 10x  - (x² - x - 6)}/(x + 2)(x + 5)

= (x² + 11x + 6)/(x + 2)(x + 5)

option B

3x/(x + 3)  + (x + 2)/x

= (3x²  + x² + 5x + 6)/(x + 3)x

= (4x² + 5x + 6)/(x + 3)x

option B
