Introduction
In algebra, trinomials are a type of polynomial expression that consists of three terms. Factoring trinomials is an essential skill in mathematics, as it allows us to simplify complex expressions and solve equations. In this article, we will explore how to match trinomials with their factors, focusing on the given trinomials and their corresponding factors.
Understanding Trinomials and Their Factors
A trinomial is a polynomial expression that consists of three terms, which can be added, subtracted, or multiplied together. The general form of a trinomial is:
ax^2 + bx + c
where a, b, and c are constants, and x is the variable.
The factors of a trinomial are the expressions that, when multiplied together, result in the original trinomial. For example, the trinomial x^2 + 5x + 6 can be factored as (x + 2)(x + 3).
Matching Trinomials with Their Factors
Now, let's focus on the given trinomials and their corresponding factors:
1.
To match this trinomial with its factors, we need to find two expressions that, when multiplied together, result in the original trinomial. We can start by listing the factors of 20, which are:
- 1 and 20
- 2 and 10
- 4 and 5
We can then try to combine these factors in different ways to see if we can create a trinomial that matches the given expression.
After some trial and error, we find that the factors of the trinomial are:
This is because .
2.
To match this trinomial with its factors, we can follow the same process as before. We need to find two expressions that, when multiplied together, result in the original trinomial.
After some trial and error, we find that the factors of the trinomial are:
This is because .
