Maths Help.
 

Anyone out there really good at maths?

It's been ages since I've done anything complicated and I've completely forgotten lots of it.

Anyone know how to solve:

18x^3 + 340x = 6351 :confused:

Lol. Didn't think so. Google didn't particularly help.

I had got 6.175 using an approximation (needed Google to jog my memory though) but 6.18053 works out almost exactly. Useful site for O-level maths, if we had the internet back then ;)

Brilliant. Thanks guys. We'd got it to 'just over 6', but needed a bit more of an accurate answer than that.

This is the problem with all the good software these days - it makes you forget all the useful stuff you've learned.

You mean there was useful stuff to learn. Bugger!
