Solved Examples

Step 1

  1. Divide 2x22x^2 by xx. Result 2x2x. This is first term of quotient.

Step 2

  1. Multiply (x+2)(x+2) by 2x2x: 2x2+4x2x^2 + 4x. Subtract this from dividend.

Step 3

  1. (2x2+3x+1)(2x2+4x)=x+1(2x^2 + 3x + 1) - (2x^2 + 4x) = -x + 1. New dividend is x+1-x + 1.

Step 4

  1. Divide x-x by xx. Result 1-1. Second term of quotient.

Step 5

  1. Multiply (x+2)(x+2) by 1-1: x2-x - 2. Subtract.

Step 6

  1. (x+1)(x2)=3(-x + 1) - (-x - 2) = 3. Remainder is 3.
Final Answer

Quotient: 2x12x-1, Remainder: 3
