factorise (+2x+54

Answer 2

Answer:

212x + 324z - 21zx + 2916

Step-by-step explanation:

i] [-2x + 54 -3z]^2

ans>  [-2x + 54 - 3z]  [-2x + 54 - 3z]

   =    4x - [54 x 2x] + [2x x 3z] - [54 x 2x] + [54 x 54] - [54 x 3z] + [3z x 2x]                  - [54 x 3z] + [3z x 3x]

    =    4x - 108x + 6xz -108x + 2916 - 162z + 6zx - 162z + 9zx

    =   2916 - 212 - 324z + 21zx    

     {212x + 324z - 21zx + 2916}
