You can put this solution on YOUR website! (2x^3-5x^2+7x-1)/(x-1)..............put x-1=0...x=1
1|...2...............-5............7.............-1
.....0................2............-3.............4
------------------------------------------------------
.....2................-3...........4..............3
hence...remainder =3...and....
quotient is.....2x^2-3x+4
