Question

simplify 2a(a-b²) - 3b(ab+2a) - ab(a+b)​

Answer 1

Answer:

a ( 2a - 6b^2 - 6b - ba)

Step-by-step explanation:

2a(a-b²) - 3b(ab+2a) - ab(a+b)

= 2a^2 - 2ab^2 - 3ab^2 -6ab - ba^2 - ab^2

= 2a^2 (- 2ab^2 - 3ab^2 - ab^2) - 6ab - ba^2

= 2a^2 - 6ab^2 - 6ab - ba^2

= a ( 2a - 6b^2 - 6b - ba)
