Step-by-step explanation:
Solving the question in parts. First solving numerator which is [ x² - ( x + 1 )( x + 2 ) ].
x² - [ ( x + 1 )( x + 2 ) ]
x² - [ x( x + 2 ) + 1( x + 2 ) ]
x² - [ x²+ 2x + x + 2 ]
x² - x² - 3x - 2
- 3x - 2
Therefore, on simplifying the denominator we get - 3x - 2
Therefore, [ x - ( x + 1 )( x + 2 ) ] = - 3x - 2
