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 a. Multiply the (a + 2) by a 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 –10. Multiply the (a + 2) by –10 and subtract.
The quotient is a – 10, and the remainder is – 6. Therefore,
\
