Explanation:

See attached picture.

First, compare the highest term of the dividend (x²) to the highest term of the divisor (x). We need to multiply the divisor by x.

When we do that, we get x² + 5x. Subtracting this from the dividend, we get -9x + 11.

Now repeat the process. Compare the highest term of the new dividend (-9x) to the highest term of the divisor (x). We need to multiply by -9.

When we do that, we get -9x − 45. When we subtract from the new dividend, we get 56.

So the quotient is x − 9, and the remainder is 56.
