Expand and simplify?

distribute first what is in parenthesis and then multiply by 3:

illustrated below:

( 6w - 11x) ( w + 3x)
First FOIL:

F: 6w^2
O: + 18wx
I: -11wx
L: -33x^2

3 ( 6w^2 + 7 wx - 33x^2)

18w^2 + 21wx - 99x^2 <----- FINAL ANSWER

hope this helps

3 ( 6 w ² + 7 w x - 33 x ² )
18 w ² + 21 w x - 99 x ²

3(6w - 11x)(w + 3x)

=(18w - 33x)(w + 3x)

=18w^2 + 54 wx - 33 wx + 99 x^2

=18 w^2 + 21wx + 99 x^2

18w^2+21wx-99x^2

3(6w-11x)(w+3x)

(18w-33x)(w+3x)

18w square + 54wx-33wx+ 99x square

18w square + 21wx + 99x square.

that's your answer.

3(6w - 11x)(w + 3x)

[3(6w - 11x)](w + 3x)

(18w - 33x)(w + 3x)

18w^2 + 54 wx - 33 wx + 99 x^2

18 w^2 + 21wx + 99 x^2
