Find the product:ab(a2 – b2) – InterviewSolution

1.	Find the product:ab(a2 – b2)
Answer» ab(a² – b²) 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) … [∵ a^m × aⁿ = a^m+n]

Find the product:ab(a2 – b2)

Answer»

ab(a² – b²)

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) … [∵ a^m × aⁿ = a^m+n]
