Question

Easy way to Multiply polynomials?

Answer 1

(a+b)^x <= like this? use binomial expansion.

Answer 2

multiply everything in one polynomial, by everything in the other :)

Answer 3

(x+y+z)(a+b+c) is xa+xb+xc+ya+yb+yc+za+zb+zc :D

Answer 4

(a+b)^2 = a^2 + 2ab + b^2
(a+b)^3 = a^3 + 3a^2b + 3ab^3 + b^3

There is a generalized form of this. and its pretty cool. Look it up!

Answer 5

laxmonster, it will depend on whether your x is a non-negative integer or something more general.

Answer 6

Is x a natural number or something else?

Answer 7

he had asked earlier about the basic laws of math, so i think we can assume his problem sets are simple

Answer 8

Technically, the binomial expansion will work for *any* x, but the form you get will depend on what it is.

Answer 9

okay
