Simplifying Polynomial Expressions

This article will guide you through simplifying the following polynomial expression:

(2x³ + 7x² + x) + (2x² - 4x - 12)

Understanding Polynomials

Polynomials are algebraic expressions consisting of variables and constants, combined using addition, subtraction, and multiplication, where exponents of variables are non-negative integers.

Simplifying the Expression

  1. Identify Like Terms:

    • Like terms have the same variables raised to the same powers.
    • In our expression, we have:
      • x³ terms: 2x³
      • x² terms: 7x² and 2x²
      • x terms: x and -4x
      • Constant terms: -12
  2. Combine Like Terms:

    • Add the coefficients of the like terms.
    • (2x³ + 7x² + x) + (2x² - 4x - 12) = 2x³ + (7x² + 2x²) + (x - 4x) - 12
  3. Simplify:

    • Combine the coefficients: 2x³ + 9x² - 3x - 12

Final Result

The simplified form of the expression (2x³ + 7x² + x) + (2x² - 4x - 12) is 2x³ + 9x² - 3x - 12.
