Simplifying the Expression: (x^2-4x-10)+(x^2-9x+3)

In algebra, we often encounter expressions involving multiple terms and variables. Simplifying these expressions makes them easier to understand and manipulate. Let's look at how to simplify the expression (x^2-4x-10)+(x^2-9x+3).

Understanding the Expression

The expression contains two sets of parentheses, each representing a polynomial. Here's a breakdown:

  • (x^2 - 4x - 10): This is a trinomial with a quadratic term (x^2), a linear term (-4x), and a constant term (-10).
  • (x^2 - 9x + 3): Another trinomial with a quadratic term (x^2), a linear term (-9x), and a constant term (+3).

Simplifying the Expression

To simplify, we combine like terms. Remember, like terms have the same variable and exponent.

  1. Identify Like Terms:

    • x^2 terms: x^2 and x^2
    • x terms: -4x and -9x
    • Constant terms: -10 and +3
  2. Combine Like Terms:

    • x^2 + x^2 = 2x^2
    • -4x - 9x = -13x
    • -10 + 3 = -7
  3. Write the Simplified Expression: The simplified expression is 2x^2 - 13x - 7.

Conclusion

By identifying and combining like terms, we successfully simplified the expression (x^2-4x-10)+(x^2-9x+3) to 2x^2 - 13x - 7. This simplified form allows for easier manipulation and understanding of the expression.
