Which expression is equivalent to 3 (x+2) (3x-1)

3 (x+2) (3x-1) = 3• (x+2) • (3x+1).

1. Distribute the 3 across x+2 to get (3x+6) • (3x-1)

2. Distribute the 3x term from the first expression across the 3x-1. And then do the same with the 6.

9x^2-3x+18x-6

And then combine like terms

9x^2+15x-6

Answer: 9x2 + 15x - 6

Step-by-step explanation: (3x + 6) (3x - 1)

9x2 - 3x + 18x - 6

= 9x2 + 15x - 6
