(3x-5)(x-2) As A Trinomial

Expanding (3x-5)(x-2) into a Trinomial

This article will guide you through the process of expanding the expression (3x-5)(x-2) into a trinomial.

Understanding the Process

Expanding a product of binomials involves applying the distributive property. In essence, we multiply each term in the first binomial by each term in the second binomial.

Step-by-Step Expansion

  1. Distribute the first term of the first binomial:

    • (3x)(x-2) = 3x² - 6x
  2. Distribute the second term of the first binomial:

    • (-5)(x-2) = -5x + 10
  3. Combine the results from steps 1 and 2:

    • (3x² - 6x) + (-5x + 10) = 3x² - 11x + 10

The Trinomial Result

Therefore, the expanded form of (3x-5)(x-2) as a trinomial is 3x² - 11x + 10.

Key Points

  • The resulting trinomial has a leading coefficient of 3, a linear coefficient of -11, and a constant term of 10.
  • Expanding binomials is a fundamental skill in algebra and is used in various applications, including solving equations and factoring expressions.
