We have  ( x +  2 ) ( x +  3 ) + ( x - 3 ) ( x -  2 ) - 2x ( x +  1 ) = 0

So,

⇒( x2 +  3x  + 2x  + 6 )  +( x2 -  3x  - 2x  + 6 ) - ( 2x2 + 2x ) = 0

⇒( x2 +  5x  + 6 )  +( x2 -  5x  + 6 ) - ( 2x2 + 2x ) = 0

 ⇒x2 +  5x  + 6  +  x2 -  5x  + 6 -  2x2 - 2x  = 0

⇒12  - 2x  =  0

⇒2x  =  12

⇒x  =  6  ( Ans )
