So that means you are weak in MATHS
I never said I was good at maths? lol im taking my GCSEs this year and if i was confronted with a question like that I would use the quadratic formular you would still get the same outcome.

Who really cares same outcome pal
But you cannot do some of the equations using your method which is also a waste of time.......you will not be able to solve in your method if we have two variables...hahaah.
If so shall i give you an equation to solve ????? (only if you are brave enough) HIKZ

I am currently in AS Level ( so you cannot solve the question I just gave without AS knowledge)
So what was the point in asking it then? The question you gave was a cubic, this whole thread is regarding quadratics. His method would not work since it uses the quadratic formula, doesn't take a genius to figure that one out. Congratulations on your A*s last year, maybe this year try to focus on not being a ****

Really...If so if he was soo INTELLIGENT , he could easily spot that is was a CUBIC

Except he never claimed to be 'soo intelligent' so that's completely irrelevant here. He gave a valid method for solving the question which OP asked, sure there are other ways but that doesn't make using the formula any less credible. I'm really not sure what your problem is, you're making some big deal out of nothing. I'd suggest you go revise for these 11 AS units and stop wasting your time with this.

He never said he was intelligent? Try not be so patronising or condescending - no one asked for your credentials here. How about I throw you a polynomial to the 7th degree with complex roots? It's the same thing as giving a GCSE student a cubic.

FINISHED REVISING
Predicted Results 11 A's for all units

That's great, good luck with them.

Can you prove that the real part of every non-trivial zero in the Riemann zeta function is 0.5?

What answer did you end up up getting for this ? I got X = 2 and X = -4
seems correct

(Original post by NNB_Herath)
Even i was in IGCSE, i was smarter than you...
ADVICE - DO NOT DO MATHS FOR AS and A2.....you will CRY
i disagree i think it's ok so far, haven't delved into A level stuff but AS matrhs seems easy enough(for mr)

Solve this with your method if you can NOOB :P
2x3-30x2+162x-350=0.
LOL quadratic formula is derived from

just guess to find a value which makes that equation = to 0 then long division from there

Assuming it is soluble in radicals?
13. Enough. Let's not go anymore off topic than this already is.
