By factoring I get x-3 divided by x+3
1 over x2 - 4 is the multiplicative inverse of x2 minus four 1/x2 - 4

X squared is not an inverse function; it is a quadratic function.
(x - 5)(x^2 + 1)
x2-5x-36 = (x-9)(x+4) when factored
x = ? 42 = x squared minus x
The answer is: X1 = 2 X2 = -7
X=1
5(x - 3)(x + 3)
