keep all the questions in one topic!!!!

Remember that you also know the distance between roots (this is what you wrote in another post

maybe this will help

sorry, i dont get it :-(

maybe i'm just to tired :-)

when ax^2 + 0x + 185 what?

hi guys

Do you have any idea where I could find some worksheets (printouts) on propositional calculus - high school?

i'm also looking for some websites with basic and intermidiate problems on mathematical

logic

I am looking for some good websites on mathematical logic (high school level).

Thanks for your help

[f(x)/g(x)]' = (f'(x)*g(x) - f(x)*g'(x))/[g(x)]^2 = (0*x - 1*1)/x^2 = -1/x^2

3. (3x^2-5)/x^2

1. Denominator: (x+4)(x+9)

high school (last three years of HS)

also looking for some good books on trigonometry

hi guys

could you please recommend some books for calculus and geometry

thanks

y = (5 - x)/3

gradient = -1/3

equation of a straight line: y = ax + b where a is a gradient.

btw, you can solve it for p. it is a quadratic equation in terms of p

terms of algebraic expression:

here we have three terms:

10p2

-2p

-1

(1/ln2)*2^x +C

in other words:

(2^x)/lna

i don't know what nationalities you have there but it's 4th house

i don't think it's possible to predict when there will be a prime number. but might be wrong :-(

i'm not sure how they distribute(divide) the prizes but i'm sure that by buying all possible combination you won't win more than you spent.

to simplify means to divide denominator and denominator by the same number :-)

7% of 9% = 7/100 of 9/100 = 7/100 * 9/100 = 63/10000

i don't get this step:

x^6 + 30x - 1 = 0

Let x^3 = y, then;

y^2 + 30y - 1 = 0

why do you have 30y if y = x^3?

step 5. there you should have absolute value.

thanks guys for quick replies.
