Answer
a2 - ab(1 - b) - b3
= a2 - ab + ab2 - b3
= (a2 - ab) + (ab2 - b3)
= a(a - b) + b2(a - b)
= (a - b)(a + b2)
Hence,a2 - ab(1 - b) - b3 = (a - b)(a + b2)

a2 - ab(1 - b) - b3
= a2 - ab + ab2 - b3
= (a2 - ab) + (ab2 - b3)
= a(a - b) + b2(a - b)
= (a - b)(a + b2)
Hence,a2 - ab(1 - b) - b3 = (a - b)(a + b2)
