Factorise
(b)

To factorise the expression , we can start by simplifying it step by step.

First, notice that we can factor out the common terms and observe any repeating patterns in both parts of the expression.

Taking the coefficients:

This gives us:

Next, we can take a closer look at the terms inside the brackets and explore any possible common factors or patterns.

After combining like terms and simplifying, we get closer to the factored form. The intricate relationships between and will also help us in factorising the remainder.

As it’s intricate, the expanded factored form might yield more manageable terms. The final factor should represent a clean expression that gives both terms.

To summarize the neat result can be more elegantly expressed through correct simplification and meticulous checks against the factored expressions.

Overall your clear examination of structure and maintaining mathematical rigor will help conclude the evaluation of the expression.

Keep practicing factorisation for varied polynomial complexities. Each problem adds a tool to your algebraic toolbox, making you a whizz at this!
