Answer:
Step-by-step explanation:
To solve this expression we have to FOIL:
1. multiply the first values in each parentheses
(3x)(3x) = [tex]9x^2[/tex]
(x times x is [tex]x^2[/tex])
2. multiply the outer values of each parentheses
(3x)(2) = 6x
(Multiply only the coefficent)
3. multiply the inner values of the parentheses
(9)(3x) = 27x
4. multiply the last values of the parentheses
(9)(2) = 18
Then add the values and combing like terms:
[tex]9x^2[/tex] + 6x + 27x + 18
[tex]9x^2[/tex] + 33x + 18
