Help on Polynomial Long Division

Introduction for long division of polynomials:
In this article let me help you with polynomial long division. Since i had shown you enough summary on polynomials. Let me directly help you with the following examples.

Example Problems for Study about Polynomial Long Division:
Study about polynomial long division - Example:
1) Divide 2x2 – 5x –2 by x -4
Solution:
Step 1: Given Divide 2x2 – 5x -2 by x - 4
Step 2: Take x - 3 and first two digits of given problems 2x2 – 5x
Step 3: Multiply x - 4with 2x then we can get 2x2- 8x.
Step 4: Then minus 2x2- 8x from 2x2 – 5x -1 and change the sign of 2x2- 8x before subtract the polynomial.
Step 5: Then we obtain 0 + 3x - 2
Step 6: After that x - 4 multiply with 3 then we can get 3x - 12.
Step 7: Change the sign then subtract 3x - 12 and x + 3. This could also help you on half angle formula.
Step 8: The solution is: 2x + 3 with remainder 10
2x +3
--------------
x -4) 2x2 – 5x –2

- 2x2 – 8x
----------------
0 + 3x - 2
(-) 3x -12
---------------
0 +10
---------------
Answer is: 2x + 3 with a remainder 10


I hope this exaplanation is very easy for you to understand. Keep reading may be in the next session let me help you on Examples of Mixtures
