The equation is Z^2-8+12/Z^2+Z-6

Question

I got this far
(Z-6)(Z-2)/(Z+2)(Z-3)

It needs to be simplified further, as far as my understanding (Z-2) and (Z+2) cannot be cancelled out.

Answer 1

I'm assuming the original equation is: (Z^2 - 8Z + 12) / (Z^2 + Z -6)

So, that 8 is actually an 8Z, right?

Answer 2

If that is the case:

Refactor the denominator (bottomm), and you'll get the right answer.

Answer 3

oh whoops, yes that is the correct equation! Thanks figured out the answer!

Answer 4

solve the problem by writtting an equation should start with "1220="and use x as the only variable
