Answer :

Sure, let's solve the expression [tex]\((2x + 3)(3x + 5)\)[/tex] step-by-step to expand it into a trinomial.

### Step-by-Step Solution

1. Distribute each term in the first binomial to every term in the second binomial:

When dealing with binomials, we use the distributive property (also known as the FOIL method for binomials which stands for First, Outer, Inner, Last).

[tex]\[ (2x + 3)(3x + 5) \][/tex]

2. Multiply the terms:

- First: Multiply the first terms in each binomial:
[tex]\[ 2x \cdot 3x = 6x^2 \][/tex]

- Outer: Multiply the outer terms in the binomial:
[tex]\[ 2x \cdot 5 = 10x \][/tex]

- Inner: Multiply the inner terms in the binomial:
[tex]\[ 3 \cdot 3x = 9x \][/tex]

- Last: Multiply the last terms in each binomial:
[tex]\[ 3 \cdot 5 = 15 \][/tex]

3. Add all these products together:
[tex]\[ 6x^2 + 10x + 9x + 15 \][/tex]

4. Combine like terms:

- Combine the [tex]\(x\)[/tex]-terms:
[tex]\[ 10x + 9x = 19x \][/tex]

- Thus, after combining these terms, you get:
[tex]\[ 6x^2 + 19x + 15 \][/tex]

### Final Trinomial

So, the expanded form of the expression [tex]\((2x + 3)(3x + 5)\)[/tex] is:

[tex]\[ 6x^2 + 19x + 15 \][/tex]

This trinomial is the product of multiplying the given binomials.
