Long division of polynomials works just like the long (numerical) division you did back in elementary school, except that now you're dividing with variables.
Example: Divide x2 – 9x – 10 by x + 1 Set up the problem like a long division
problem
Put the first variable from the outside (the divisor) into the first variable under the division sign
Multiply the answer by the advisor and place the answer under the polynomial
Subtract the two terms from the polynomial
Bring down the constant and start the process all over again
Put the first variable from the outside (the advisor) into the variable
Multiply the answer by the divisor and place the answer under the polynomial
Subtract and get a remainder of “0”
