I hope it will help you.

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

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

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

= a^2-a . a^2-2a^2 + (a^2-a-2) (-a) + (a^2-a-2 (-a^2-a-20 (-b)

= a^4-a . a^2-2a^2- (a^2-a-2) . a + (a^2-a-2) 9-b)

= a^4 -a^3-a . a^2 - +a^2 +ba+2a+2b
