Answer 1

Answer:

Step-by-step explanation:

(I) ab(a²-b²) + b³(a-2b)

a³b - ab³ + ab³ - 2b⁴

a³b + ab³ -ab³ - 2b⁴

a³b - 2b⁴

b(a³ - 2b³)

(ii) -6x²(xy + 2y²) - 3y²(2x² + y)

-6x³y - 12x²y² - 6x²y² - 3y³

-6x³y - 18x²y² - 3y³

-3y(2x² + 6x²y + y²)

(iii) 2x(x-y²) - 3y(xy+2x) -xy(x+y)

2x² - 2xy² - 3xy² - 6xy -x²y - xy²

2x² - 6xy² - 6xy - x²y

x(2x - 6y² - 6y - xy )

hope this helps ☺️
