Question

Carry out the multiplication of the expression in each of the following
(1) . 1.5a,(10a^2b-100ab^2)
(2). a^2b^2,(a^3-b^3)

​

Answer 1

Answer:

1) 1.5a(10a^2b−100ab^2)

=(1.5a) (10a^2b +−100ab^2)

=(1.5a) (10a^2b)+ (1.5a)(−100ab^2)

=15a^3b−150a^2b^2

2) a^2 b^2 (a^3−b^3)

=(a^2b^2) (a^3+−b^3)

=(a^2b^2) (a^3)+(a^2b^2) (−b^3)

=a^5b^2−a^2b^5
