MrRissso [65]

Answer:

$6x^{2} +9x -4x+6\\$

Step-by-step explanation:

First you take 3x times 2x since its the first of both equations, which will give you 6x squared.

Then take the outer ones of both problems which is 3x times 3 which is 9x.

Then the inner, -2 times 2x which is -4x

Then the last of both individual problems which is -2 times -3 which is positive 6.
