Answer:

 =5X²-5xy+5xz-4y²-4y Ans

Step-by-step explanation:

3x(-x+y+z)  = -3x^{2}+3xy+3xz

2x(x+y+z)  = 2x^{2}+2xy+2xz

-4y(x+y+z) =-4xy-4y²-4yz

Sum

 =  2x^{2}+2xy+2xz-4xy-4y²-4y

      sum    =2x²-2xy+2xz-4y²-4y

Subtract    -3x^{2}+3xy+3xz

                  =2x²-2xy+2xz-4y²-4y-(-3x²+3xy-3xz)

                  =2x²-2xy+2xz-4y²-4y+3x²-3xy+3xz

                  =5X²-5xy+5xz-4y²-4y Ans
