Hello People. Im new hence the 1 post.

I have a problem, i recived some questions that i carnt work out, ive read books but cannot get it.

Here are so examples of problems:

Multipy:

A: (3x+3)(9x-2)

2 2

B: (x +3x)(4x -1.5x+2)

(x is squared and 4x is squared)

-1 -0.5 2

C: (x + 6x)(3+x +2x

(x with -1 at the top and 3+x with -0.5 at the top of, 2x squared.)

Can anyone work those out, and show the steps please, much appriciated.
