# Factorising watch

1. (Original post by NineOfDiamonds)
Ok so I’ve done,

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

Is this right? If so what do I do next?
I don't know if you just mistyped but it should be

Notice how this is the same as

But with and so the same factorising has happened here.

You just need to add the two terms in the bracket and you're done.

No I did put the addition signs in but it just didn’t show for some reason. I thought I couldn’t add (x+6) to (3x+4) because they should be multiplied?

No if you look at

there is a + sign between and inside the brackets so there must be a + sign between (x+6) and (3x+4).

The final step is to add together (x+6) and (3x+4).

What do I do about the 1 that is already inside the brackets? Do I add that as well?

1 times by anything is itself so you can ignore the 1.

(x+6)^3(4x+10)?

(x+6)^3(4x+10)?
Yes that's right.

Don't worry if you found that hard - most students do the first time they tackle a question like this. After practicing a few like this I'm sure you'll be fine.

Thank you very much

Which 2 terms?
You should have got it factorised as

So you add the two terms in the right hand pair of parentheses.
