3x-2x-33x−2x−3
Step 1
Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of 0.
x | - | 3 | 3x | - | 2 |
Step 2
Divide the highest order term in the dividend 3x by the highest order term in divisor x.
3 | |||||||
x | - | 3 | 3x | - | 2 |
Step 3
Multiply the new quotient term by the divisor.
3 | |||||||
x | - | 3 | 3x | - | 2 | ||
+ | 3x | - | 9 |
Step 4
The expression needs to be subtracted from the dividend, so change all the signs in 3x-9
3 | |||||||
x | - | 3 | 3x | - | 2 | ||
- | 3x | + | 9 |
Step 5
After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.
3 | |||||||
x | - | 3 | 3x | - | 2 | ||
- | 3x | + | 9 | ||||
+ | 7 |
Step 6
The final answer is the quotient plus the remainder over the divisor.
3+7x-3
