Happy to help blackjack...

If not used for 18 years you may find this site useful.


www.google.com


It is a new site, which allows you to search the Internet for the subject you are interested in.
In your example type in "quadratic equation"



X= (-b +- (x^2 -4ac)^1/2)/2a.   (A=1.  B=93.568. C= 2057.227632)

But it's not really an equation? What's on the other side of the =? 0?
Do you mean x2-93 = 2057? is it x squared?

Now then, THIS very same thing was always my downfall at school.

I was numerate (and still am) to a decent degree - but what the bloody hell are quadratic bleedin' equations??!!

I remember being told about them by the maths teacher one day at Hanley High, understanding them, doing numerous examples of them in class for the rest of the lesson - and then a total blank - for the rest of my life.

Hi toes..

They are pretty much any equation with x squared in it.

The standard way it is shown is
Y = ax^2 + bx +c

Where a,b,c are any number (although if a=0 it is just y=bx + c so a linear equation)


The formula you would have used at school is about finding the 2 points where y=0.

Mexico thanks for the help. I obviously resorted to google first and had a good look at it but even with an equation solver I didn't have a clue what was happening without as I don't remember anything of that ilk from school and what I was reading wasn't helping! I just needed someone that made sence of it, to make sense of it for me!

cheers

I think I haven't actually given the full puzzle which I didn't realise. Apologies... here is the writi9ng that coincided with the puzzle that I missed out (crucial I know, shoot me later)

Find the two roots of the following quadratic equation

x2 - 93.568x + 2057.227632 = 0
