Divide (2a^2+a+3)÷(a-1)
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.

Step 6
Pull the next terms from the original dividend down into the current dividend.
