Note on factorising

In this article let me help you on factorising. In spite of looking on the summary let me directly help you with an example on this. I hope my information on this will help you a lot.

Let us learn the methods involved in factorising in algebra.

If all the types of the expression has any common factor, then factorising in algebra could be done by taking the common factor outside.

For example:xy + yz = y(x+z)
We could do factorising in algebra using identities. This could also help us on equations of motion
x2 + 2xy + y2 = (x+y)2
x2 - 2xy + y2 = (x-y)2
x2 -y2 = (x+y)(x-y)
x2 + (a+b)x + ab = (x+a)(x+b)
