Answer 1

18 using x as 3

Explanation:

It all depends on what the x is so say I have x=3 so then it would be 18.

The sum of three x plus one times the difference of x-one.

Answer 2

3x² - 2x - 1

Explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

3x(x - 1) + 1(x - 1) ← distribute both parenthesis

= 3x² - 3x + x - 1 ← collect like terms

= 3x² - 2x - 1 ← in standard form
