3y² (243+ ay - 6x²)​

Answer 1

Answer:

729y2 + 3ay2 - 18x2y2

Step-by-step explanation:

Multiply 3y2 to each monomial

3y2 x 243= 729 y2

-multiply 3 by 243 then copy y2

3y2 x ay = 3ay3

-multiply 3 by a, 3a then y2 by y makes y3

3y2 x -6x2= -18x2y2

-multiply 3 and -6, -18

-then copy x2 and y2
