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

Explanation:

Step1: Apply the distributive property (FOIL method)

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

Step2: Simplify each product

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

Step3: Combine like terms

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

Answer:

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