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 b. Multiply the (b + 1) by b 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 –5b. Multiply the (b + 1) by –5b 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 6. Multiply the (b + 1) by 6 and subtract.

The quotient is  , and the remainder is – 8. Therefore,

.
