>2 means squared

factorise=

x>2 - 4 / x>2 - x - 6

________ _________

x>2-7x+10 x>2 - 3x+1-

now that i see this under the quote image(which you can't see unless you qoute his)... there are two fractions.. and from what i am gonna assume, these two fractions are being divided..

x>2 -4

________

x>2-7x+10

thats fraction one

x>2 - x - 6

_________

x>2 - 3x +1 (assuming the "-" is a typo as well..)

thus... its a division problem, so flip the secon equation to:

x>2 -3x + 1

__________

x>2 - x - 6

then it becomes a multiplication problem with fractions..

x>2 -4 x>2 -3x +1

________ * ___________

x>2-7x+10 x>2 - x - 6

so.. we need to make the bottom equations match, but first, lets factor these out into simpler bits..hmmmm the tops can be factoed as well..

fraction 1:

x>2 - 4 = (x+2)(x-2)

x>2 - 7x + 10 = (x-5)(x-2)

fraction 2:

*top can't be factored*

x>2 - x -6 = (x+2)(x-3)

so.. the new eqautions would be:

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

_________ * ____________

(x-5)(x-2) (x+2)(x-3)

so much simpler now.. now we cross similar factors out....

1 x>2 -3x +1

__________ * ___________

(x-5) (x-3)

now lets multiply:

x-5)(x-3) = x>2 -3x -5x +15 = x>2 - 8x+15

x>2 -3x + 1

____________

x>2 - 8x+15

this is the answer i came up with.. i will now re read making sure i didn't mistype anythign screwing myself up

EDIT: view under the quote option, this forum does NOT handle multiple spaces thus squishing my equations together!

EDIT2: if he typod the bottom right of his starting eqation, and meant x>2 -

**2**x +1 then it could be factored cleanly.. secondly i could also make use of the quadratic eqaution, but doing that in the computer would be difficult, and the asnwers wouldn't come out clean either...
