Yeah...not even going to try that one. I have other things I must dwell on. Sorry I haven't been able to assist in answering anything today; Tuesdays and Thursdays are especially busy for me. I'll try to help tomorrow, but no promises! I'm a busy man....I do enjoy helping people out, though!

Stu:

in fact please calculate in steps the following,

-6 + Sqrt 6²-4*2*3 /2*3 include parenthesis please.
I got x1=-0.634

if m answer is right don't worry to solve. thanks

thanks melody, I see they will not always be nice simple numbers do I round of at 3 decimal placings as a rule?

Okay, perhaps I crossed a line. I apologize for my behaviour (I'm not being sarcastic).

Stu:

:D

OK, so I get the quadratic formula. it ain't such a tough nut rather it is more like a gentle baby. but to save upsetting it on this day of romance I'd like to resolve one thing about square rooting in maths/this formula.

assuming you are solving x²+3x+1=0

after half of the formula I have [-3 - Sqrt (+9-4)] / (2*1).. my question is simple and two part.

1) to Sqrt the 9 I must also Sqrt the 4 or calculate the sum of 9-4 then Sqrt before manipulating change from outside the Sqrt right?
You have to find 9-4 =5 and THEN take the square root.
2) please insert parenthesis to solve including signs.
