Solution

                         x – 3
`x - 2")"overline(x^3 - 3x^2 + 5x - 3)`
           x3             – 2x
           –                 +            
           – 3x2 + 7x – 3
           – 3x2         + 6
           +                –             
                        7x – 9

Quotient q(x) = x – 3

Remainder r(x) = 7x – 9
