Answer:
12/30
Step-by-step explanation:
So we know that the denominator-numerator=18
And we also know that it's equal to 4/10 or 2/5.
Soooooooooooooo the most easiest is just to trial and error: 12/30
But I don't really know the more complex formula...
No values of z make the equations true.

By the quadratic formula,
Then
Multiply numerator and denominator by the denominator's conjugate:
So if you wanted the factored form (exg. 1*2*3*4=24)
then this is (5 times 5 times 7)
