Pre-Algebra Examples

Divide (4x-x^2)/(x^2+2x-8)
Step 1
Reorder and .
Step 2
Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of .
+--++
Step 3
Divide the highest order term in the dividend by the highest order term in divisor .
-
+--++
Step 4
Multiply the new quotient term by the divisor.
-
+--++
--+
Step 5
The expression needs to be subtracted from the dividend, so change all the signs in
-
+--++
++-
Step 6
After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.
-
+--++
++-
+-
Step 7
The final answer is the quotient plus the remainder over the divisor.
