3(3)^2 + 3(3) + 12 means 3*32 + 3*3 + 12 or 3*9 + 9 + 12 or  27 + 9 + 12  or  48.

User PEMDAS.... Parentheses first, exponents next, multiplication and division next, and addition and subtraction last.

 

This will get you 3*9+9+12.

                          =27+9+12

                          =48.

 

Hope this helped!
