Use foil (first, outer, inner, last)
First terms: 3x * 6x = 18x²
Outer terms: 3x * 1 = 3x
Inner terms: - 2 * 6x = - 12x
Last terms: - 2 * 1 = - 2
Put all that together to get 18x² + 3x - 12x - 2
3x and - 12x can be combined because they're like terms; 3x - 12x = - 9x
So the final product is 18x² - 9x - 2

18x² - 9x - 2
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
3x (6x + 1) - 2 (6x + 1) ← distribute both parenthesis
= 18x² + 3x - 12x - 2 ← collect like terms
= 18x² - 9x - 2
