You can use 920 divided by 20. This would give you 46. You get 920 by Round 921 to the nearest tens. You also get 20 by rounded it to the nearest tens
( x² + 2 x + 1 ) / ( x - 2 ) / ( x² - 1 ) / ( x² - 4 ) =
= ( x² + 2 x + 1 )·( x² - 4 ) / ( x - 2 )·( x² - 1 ) =
= ( x + 1 )²·( x - 2 )·( x + 2 ) / ( x - 2 )·( x - 1 )·( x + 1 ) =
= ( x + 1 )·( x + 2 ) / ( x - 1 )
