Divide Using Long Polynomial Division (x^3-3x^2-5x-25)÷(x-5)


Step 1
Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of .
----

Step 2
Divide the highest order term in the dividend by the highest order term in divisor .
----

Step 3
Multiply the new quotient term by the divisor.
----
+-

Step 4
The expression needs to be subtracted from the dividend, so change all the signs in
----
-+

Step 5
After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.
