G (x) = ( x + 3 ) ( x+ .3 + 5 ) = ( x + 3 ) ( x+ 8 )
H (x) = ( x + 1 ) ( x - 3 + 2 x - 7 ) = ( x + 1 ) ( 3 x- 10 )
I (x) = ( x + 1 ) ( x - 3 - 2 x + 7 ) = ( x + 1 ) ( - x + 4 )
J (x) = ( 2 x - 3 ) ( x + 1 + 2 x - 3 ) = ( 2 x - 3 ) ( 3 x - 2 )
k ( x) = ( x + 1 ) ( 2 x - 3 + 5 x + 5 ) = ( x + 1 ) ( 7 x + 2 )
