Question

let us factorise the following​

Answer 1

Step-by-step explanation:

What is decomposition? Decomposition is the first stage in the recycling of nutrients that have been used by an organism (plant or animal) to build its body. It is the process whereby the dead tissues break down and are converted into simpler organic forms.

Answer 2

Factorise the following:

• $\\ \implies\sf { a²(b-c)²-b²(c-a)²}$

Step by step explanation:

$\\\implies\sf { \{a(b-c)\}²-\{b(c-a)\}²}$

$\implies\sf { \{ab-ac)\}²-\{bc-ba)\}²}$

${\implies\sf { (ab-ac+bc-ba)(ab-ac-bc+ba)}}$

${\implies\bf { (bc - ac)(2ab-ac-bc)}}$
