# Factorising watch

1. Can someone explain to me how I do this question please?
2. Bump
3. Take out a factor if (x+6)^3 first and then simplify

I don’t know what you mean? :/

Can you factorise this? Then think about how this is similar to what you have.

Is it z(y³ + y⁴/z) ?

No the common factor here is so you need to take that outside the brackets.

You need to be confident with this type of factorising before you’ll be able to understand the question in your original post.

Ok so I’ve done,

(x+6)^3 (1(x+6))(3x+4).

Is this right? If so what do I do next?

No, it's not right.

What do you get?

y^3(y+z)

y^3(y+z)
Good. How is this like your original question?

Because (x+6)^3 is the highest factor of the first two terms. Why can’t I factorise that out like I did?

You forgot the addition sign between (x+6) and (3x+4)
15. Is this higher tier maths? Or foundation?

Higher tier FM
18. (Original post by NineOfDiamonds)
In any case, the next step would simply be to add the two terms and then you're done.

Makes sense, still building up to higher tier algebra at the moment, only just learned factorising and expanding so I tried to do this question with foundation tier knowledge.

Which 2 terms?
