1/4(a-b)^2x(b-a)^3x(-a-b)^5x(2a+2b)^4

1/4(a-b)^2x(b-a)^3x(-a-b)^5x(2a+2b)^4
1/4(a-b)^2x(b-a)^3x(-a-b)^5x(2a+2b)^4

1/4(a-b)^2x(b-a)^3x(-a-b)^5x(2a+2b)^4
1/4(a-b)^2 x (b-a)^3 x (-a-b)^5 x (2a+2b)^4
= 1/4(a-b)^2 x {-(a-b)^3} x {-(a+b)}^5 x {2 (a+b)}^4
= 1/4 × (-1) × (-1) x 2^4 × (a-b)^(2+3) × (a+b)^(5+4)
= 4 × (a-b)^5 × (a+b)^9
