Explanation:

Step1: Apply distributive property (FOIL)

Multiply each term in the first binomial by each term in the second binomial:
$(3x)(x) + (3x)(-1) + (1)(x) + (1)(-1)$

Step2: Simplify each product

Calculate each term:
$3x^2 - 3x + x - 1$

Step3: Combine like terms

Combine the middle terms ($-3x$ and $x$):
$3x^2 - 2x - 1$

Answer:

$3x^2 - 2x - 1$
