Re: C3 Algebraic FractionsIn order to express this as a single fraction, you need both of the above terms to have a common denominator. You should be able to see that denominators of both terms already have a common factor of x-3. Try multiplying the first fraction by(Original post by Vinkal)
EXPRESS
(x-10)/((x-3)(x+4))-(x-8)/((2x-1)(x-3))
AS A SINGLE FRACTION IN ITS SIMPLEST FORM.
THANK YOU
and the second by 
, thinking about why this is valid and why it helps.

Re: C3 Algebraic FractionsCannot be simplified(Original post by Vinkal)
thank you
so i got (x-14)/((x+4)(2x-1)) can that be simplified or is it in its simplest form -

Re: C3 Algebraic FractionsSince the numerator is linear whilst the denominator is a quadratic (importantly expressed in it's simplest form), this can only be simplified further if the numerator is some multiple of one of the two linear factors in the denominator. Is this the case?(Original post by Vinkal)

Re: C3 Algebraic Fractions(x-10)/((x-3)(x+4))-(x-8)/((2x-1)(x-3))
(X-10)(2X-1) (X-8)(X-3 )
(X-3)(X+4)(2X-1) - (X-3)(X+4)(2X-1)
(2X2-21X+10) (X2 -4X-32 )
(X-3)(X+4)(2X-1) - (X-3)(X+4)(2X-1)
(X2-17X+42)
(X-3)(X+4)(2X-1)
(X-3)(X-14)
(X-3)(X+4)(2X-1)
(X-14)
(X+4)(2X-1)Last edited by Vinkal; 15-09-2012 at 21:31. -

Re: C3 Algebraic FractionsHope that was not in response to my deleted post where I had made an error(Original post by Vinkal)
(x-10)/((x-3)(x+4))-(x-8)/((2x-1)(x-3))
(X-10)(2X-1) (X-8)(X-3 )
(X-3)(X+4)(2X-1) - (X-3)(X+4)(2X-1)
(2X2-21X+10) (X2 -4X-32 )
(X-3)(X+4)(2X-1) - (X-3)(X+4)(2X-1)
(X2-17X+42) (X-3)(X+4)(2X-1)
(X-3)(X-14) (X-3)(X+4)(2X-1)
(X-14) (X+4)(2X-1)
To help in the future ... this gives fractions
