Solution

For this case we can do the following to model the function f(x)

[tex]f(x)=g(x)(x-a)+r[/tex]

Where g(x) os the quotient and r the remainder and replacing we got:

[tex]f(x)=(3x^2-x+2)\cdot(4x-5)-1[/tex]

And solving we got:

[tex]f(x)=12x^3-15x^2-4x^2+5x+8x-10-1[/tex]

And if we simplify we got:

[tex]f(x)=12x^3-19x^2+13x-11[/tex]
