4 / x - 1 - 5 / x + 2 = 3/2
[ 4( x + 2 ) - 5( x - 1 ) ] / ( x - 1 ) ( x + 2 ) = 3/2
( 4x + 8 - 5x + 5 ) / ( x² + 2x - x - 2 ) = 3/2
( - x + 13 ) / x² + x - 2 = 3/2
Cross multiplying
3 ( x² + x - 2 ) = 2 ( - x + 13 )
3x² + 3x - 6 = - 2x + 26
3x² + 3x + 2x - 6 - 26 = 0
3x² + 5x - 32 = 0
The sum cannot be simplified after this , please check your question once and repost it .
