Question

(a^2-b) (a-b^2) +(a-b)^2​

Answer 1

Answer:

a^3 - a^2b^2 - 3ab +a^2 + b^2 - b^3

Answer 2

Answer:

(a^2-b) (a-b^2) +(a-b)^2

=

$({a}^{2} - b)(a - {b}^{2} ) + {(a - b)}^{2}$

=

$= {a}^{3} - {a}^{2} {b}^{2} - ab + {b}^{3} + {a}^{2} + {b}^{2} - 2ab \\ = {a}^{3} + {b}^{3} - {a}^{2} ( {b}^{2} - 1) + {b}^{2} - 3ab$

Hope it may helps
