Math Problem Statement

Adding and Subtracting Polynomials: (3 - 2x + 3x square) + (7 + 6x - 2x square)

Solution

To add the polynomials (32x+3x2)(3 - 2x + 3x^2) and (7+6x2x2)(7 + 6x - 2x^2), follow these steps:

Step 1: Arrange the terms of each polynomial in standard form (order terms by decreasing powers of xx):

  • (32x+3x2)(3 - 2x + 3x^2) becomes 3x22x+33x^2 - 2x + 3
  • (7+6x2x2)(7 + 6x - 2x^2) becomes 2x2+6x+7-2x^2 + 6x + 7

Step 2: Add the corresponding terms:

  • For x2x^2-terms: 3x2+(2x2)=x23x^2 + (-2x^2) = x^2
  • For xx-terms: 2x+6x=4x-2x + 6x = 4x
  • For constant terms: 3+7=103 + 7 = 10

Step 3: Combine the results:

The sum of the polynomials is:

x2+4x+10x^2 + 4x + 10

Final Answer:

(32x+3x2)+(7+6x2x2)=x2+4x+10(3 - 2x + 3x^2) + (7 + 6x - 2x^2) = x^2 + 4x + 10
