Respuesta :

We are asked to perform the long division on the following expression.

[tex]\frac{(19x^3-5x^2+6x-2)}{(x+1)}[/tex]

Let us perform the long division.

So, we have

Quotient: q(x) = 19x^2 - 24x + 30

Remainder: r(x) = -32

Divisor: b(x) = x + 1

Therefore, the equivalent expression is

[tex]19x^2-24x+30-\frac{32}{(x+1)}[/tex]

The 3rd option is the correct answer.
