(6x2 + 7x - 3) / (9x2 - 6x + 1)

All the 2's mean squared--> to the power of 2
And the x's DON'T mean multiply

You have to factorioze each expression, then cancel appropriately.

To factorize the top line, notice that 6 = 3 x 2 and 3 = 3 x 1, which gives some clues. After a while, you find

6x2 + 7x - 3 = (3x-1)(2x+3)

Now you try the bottom line!

on simplifying 6x2 + 7x - 3 you will get (3x-1)(2x + 3 )
and on simplfting 9x2 - 6x + 1 the asn will be (3x - 1) ^2
so you can cut 3x - 1
the asn will be 2x + 3/3x - 1

So to start:
(36+7x-3) (81-6x+1)
combining like terms: 117+x-2

not totally sure but this is the way I was shown

Well, let's see, can we factor these?

x = (-7 +/- sqrt(49 - 4 * 6 * -3))/(2 * 6)
x = (-7 +/- sqrt(49 +72))/(12)
x = (-7 +/- sqrt(121))/(12)
x = (-7 +/- 11)/12
x = -18/12 or x = 4/12
x = -3/2 or x = 1/3
(3x -1)(2x + 3)

The second one is easier to factor
(3x - 1)(3x - 1)

So rewrite as
((3x -1)(2x + 3))/((3x - 1)(3x - 1))

You can cancel out (3x - 1)/(3x - 1)

(2x + 3) / (3x - 1)

Factor the top to get: (3x-1)(2x+3)
Factor the bottom to get: (3x-1)(3x-1)
Notice that there is a (3x-1) term on the top and the bottom--cancel 1 from each. Now you should have: (2x+3)/(3x-1).

is it (6x^2 +7x - 3) / ( 9x^2 - 6x +1) ?

hmm.. is the answer need to be specified wat is the value of x or in the answer with the x it self??

[(3x-1)(2x+3)] / [(3x-1)(3x-1)]

=(2x+3)/(3x-1)
