Divide (t^3-3t^2+7t+12)÷(t+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 .
+-++
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.
+-++
