Plz Check the Question Again I thinks its X raise to 4 and not 4 multiplied by (x - y)

Or i would be (x-y) raise to 2 that is its square and not 2 multiplied by (x - y)

its raise to 2

1) Simplify 4(x−y)×2 to 8(x−y)

8(x−y)−12(x−y)(x+y)+9(x+y)×2

2) Simplify 9(x+y)×2 to 18(x+y)

8(x−y)−12(x−y)(x+y)+18(x+y)

3) Expand

8x−8y−12 −12xy+12yx+12 +18x+18y

4) Gather like terms

(8x+18x)+(−8y+18y)−12x2+(−12xy+12xy)+12y2

5) Simplify

26x+10y−12x2+12y2
