Question

question 7
express as a trinomial.
(3x + 8)(3x + 1)

Explanation:

Step1: Apply FOIL method

Multiply the First terms: \(3x \times 3x = 9x^2\)
Multiply the Outer terms: \(3x \times 1 = 3x\)
Multiply the Inner terms: \(8 \times 3x = 24x\)
Multiply the Last terms: \(8 \times 1 = 8\)

Step2: Combine like terms

Combine the middle terms: \(3x + 24x = 27x\)
So the expression becomes \(9x^2 + 27x + 8\)

Answer:

\(9x^2 + 27x + 8\)
