express as a trinomial.
$(x + 7)(3x + 1)$

Explanation:

Step1: Apply distributive property (FOIL)

Multiply each term in the first binomial by each term in the second binomial:
\(x \cdot 3x + x \cdot 1 + 7 \cdot 3x + 7 \cdot 1\)

Step2: Simplify each term

\(3x^2 + x + 21x + 7\)

Step3: Combine like terms

\(3x^2 + (x + 21x) + 7 = 3x^2 + 22x + 7\)

Answer:

\(3x^2 + 22x + 7\)
