Answer:

32 or 52 depending on the question.

Step-by-step explanation:

6x2 - 2y2 =                                               6x^2 - 2y^2 =

6(3)2 - 2(1)2 =                                         6(3)^2 - 2(1)^2 =

12(3) - 4(1) =                                               6(9) - 2(1) =

 36 - 4 =                                                        54 - 2 =
