How to factoring Binomial?..

OpenStudy (anonymous):

There are many ways.

OpenStudy (anonymous):

Post the problem.

OpenStudy (anonymous):

For example: x^ - 4 = x^2 - 2^2 = (x + 2)(x - 2)

OpenStudy (anonymous):

It depends on the binomial.

OpenStudy (anonymous):

Ex. \[x^{8}-y ^{8}\]

OpenStudy (anonymous):

how to solve that..?...

OpenStudy (anonymous):

\( x^{8}-y ^{8} = (x-y) (x+y) \left(x^2+y^2\right) \left(x^4+y^4\right) \)

OpenStudy (anonymous):

(x^4)^2 - (y^4)^2 = (x^4 - y^4)(x^4 - y^4) Keep simplifying to get: (x + 2)(x - 2)(x^2 + y^2)(x^4 + y^4)

OpenStudy (anonymous):

What will be the answer?..

OpenStudy (anonymous):

answer is \[ (x-y) (x+y) \left(x^2+y^2\right) \left(x^4+y^4\right) \]

OpenStudy (anonymous):

Factorising means breaking the given expression to express it in terms of its factors.

OpenStudy (anonymous):

And remember, there is no particular way of factorising a binomial.

OpenStudy (anonymous):

How abou this...?.. *\[9x^{2}y ^{2}-16w ^{2}\] \[* x4^{n}-y6^{n}\] ?...

OpenStudy (anonymous):

pls..help...
