Find the Remainder (3x^2-14x-49)/(x-7)


Step 1
To calculate the remainder, first divide the polynomials.

Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of .
---
Divide the highest order term in the dividend by the highest order term in divisor .
---
Multiply the new quotient term by the divisor.
---
+-
The expression needs to be subtracted from the dividend, so change all the signs in
---
-+
After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.
---
-+
+
Pull the next terms from the original dividend down into the current dividend.

+-
Divide the highest order term in the dividend by the highest order term in divisor .

Since the remander is , the final answer is the quotient.

Step 2
Since the final term in the resulting expression is not a fraction, the remainder is .
