When multiplying a binomial like (3+7x)(6+2x) your first steps are correct.

`(3+7x)(6+2x) = 3*6+3*2x+7x*6+7x*2x`

This equals:  `18+6x+42x+14x^(2)`

`18+48x+14x^(2)`

Therefore the final answer is:

`14x^(2)+48x+18`

(3+7x)(6+2x) 

Solve using FOIL (First, Outside, Inside, Last)

First terms: 3x6 = 18

Outside terms: 3 x 2x = 6x

Inside terms: 7x x 6 =42x

Last terms = 14x^2

So... 18+6x+42x+14x^2 = 14x^2+48x+18
