ADDING POLYNOMIALS

1.) (5x⁴ - 3x² + 4) + (6x³ - 4x² - 7)

  • (5x⁴ - 3x² + 4) + (6x³ - 4x² - 7)

  • 5x⁴ - 3x² + 4 + 6x³ - 4x² - 7

  • 5x⁴ + 6x³ - 3x² - 4x² + 4 - 7

  • = 5x⁴ + 6x³ - 7x² - 3

======================================

2.) -7x³y + 4x²y² - 2 and 4x³y + 1 - 8x²y²

  • (-7x³y + 4x²y² - 2) + (4x³y + 1 - 8x²y²)

  • -7x³y + 4x²y² - 2 + 4x³y + 1 - 8x²y²

  • -7x³y + 4x³y + 4x²y² - 8x²y² - 2 + 1

  • = -3x³y - 4x²y² - 1

======================================

3.) (5 + 24y³ - 7y²) + (-6y³ + 7y² + 5)

  • (5 + 24y³ - 7y²) + (-6y³ + 7y² + 5)

  • 5 + 24y³ - 7y² - 6y³ + 7y² + 5

  • 24y³ - 6y³ - 7y² + 7y² + 5 + 5

  • = 8y³ + 10

======================================

4.) (2x⁵ - 6x³ - 12x² - 4) + (-11x⁵ + 8x + 2x² + 6)

  • (2x⁵ - 6x³ - 12x² - 4) + (-11x⁵ + 8x + 2x² + 6)

  • 2x⁵ - 6x³ - 12x² - 4 - 11x⁵ + 8x + 2x² + 6

  • 2x⁵ - 11x⁵ - 6x³ - 12x² + 2x² + 8x - 4 + 6

  • = -9x⁵ - 6x³ - 10x² + 8x - 2

======================================

5.) (3y⁵ - 2y + y⁴ + 2y³ + 5) and (2y⁵ + 3y³ + 2 + 7)

  • (3y⁵ - 2y + y⁴ + 2y³ + 5) + (2y⁵ + 3y³ + 2 + 7)

  • 3y⁵ - 2y + y⁴ + 2y³ + 5 + 2y⁵ + 3y³ + 2 + 7

  • 3y⁵ + 2y⁵ + y⁴ + 2y³ + 3y³ - 2y + 5 + 2 + 7

  • = 5y⁵ + y⁴ + 5y³ - 2y + 14
