$\frac{(5 x^{3} - 6 x^{2} - 8 x + 9)}{x^{4} + 2 x^{3} + x + 1}$

Step 1

To calculate the remainder, first divide the polynomials.

Step 1.1

Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of $0$ .

$x^{4}$

$2 x^{3}$

$0 x^{2}$

$x$

$1$

$5 x^{3}$

$6 x^{2}$

$8 x$

$9$

Step 1.2

The final answer is the quotient plus the remainder over the divisor.

$0 + \frac{x^{4} + 7 x^{3} - 7 x - 6 x^{2} + 10}{x^{4} + 2 x^{3} + x + 1}$

Step 2

Since the last term in the resulting expression is a fraction, the numerator of the fraction is the remainder.

$x^{4} + 7 x^{3} - 7 x - 6 x^{2} + 10$
