Divide Using Long Polynomial Division Use the long division method to find the result when 2x^3+15x^2-16x+4 is divided by 2x-1

Use the long division method to find the result when is divided by

Step 1
Write the problem as a mathematical expression.
Use the long division method to find the result when

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.
-+-+
-+
