Answer:

We have : ( 2x − 1 )( x2 + 2x + 4) × (x4 − 8x)( 2x2 − 5x − 3 ) × ( x + 3 )( x2 − 2x )

So, we take term 2x2 - 5x - 3 , And using splitting the middle term method and get

2x2 - 6x + x - 3

2x ( x - 3 ) + 1 ( x - 3 )

( 2x + 1 ) ( x - 3 )

So, 2x2 - 5x - 3 = ( 2x + 1 ) ( x - 3 ) Substitute that and get

⇒ ( 2x − 1 )( x2 + 2x + 4) × (x4 − 8x)( 2x − 1 )( x + 3 ) × ( x + 3 )( x2 − 2x )⇒ ( 2x − 1 ) (x4 − 8x) ( x + 3 ) ( x2 + 2x + 4) ( 2x − 1 ) ( x + 3 ) ( x2 − 2x ) ⇒ (x4 − 8x) ( x2 + 2x + 4) ( x2 − 2x ) ⇒ (x4 − 8x) ( x4 − 2x3+ 2x3 − 4x2+ 4x2 −8x) ⇒ (x4 − 8x) ( x4 −8x)

⇒ 1 ( Ans
