Rewrite the expression in long division form .

Divide the first term of the dividend by the first term of the divisor

So the first term of the quotient is x. Multiply the by x and subtract.

Divide the first term of the last row by the first term of the divisor

So the next term of the quotient is . Multiply the by and subtract.

The quotient is  – x – 4, and the remainder is – 12. Therefore,

.
