Question

Find the product:
ab(a^2-b^2)

Answer 1

Answer:

=ab[(a+b)×(a-b)]

=ab(a+b)(a-b)

=a²b+ab²(a-b)

=a³b-a²b²+a²b²-ab³

=a³b-ab³

Answer 2

Answer:

Step-by-step explanation:

Let p, q and r be three monomials.

Then, by distributive law of multiplication over subtraction, we have:

P × (q – r) = (p × q) – (p × r)

Now, = (ab × a2) – (ab × b2) = (a3b + ab3) … [∵ am × an = am+n]
