Divide Using Long Polynomial Division (x^3-9)/(x^2+1)

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

Divide the highest order term in the dividend ${\displaystyle x^3}$ by the highest order term in divisor ${\displaystyle x^2}$.

Multiply the new quotient term by the divisor.

The expression needs to be subtracted from the dividend, so change all the signs in ${\displaystyle x^3+0+x}$

After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.

Pull the next term from the original dividend down into the current dividend.
