<span>Solutions or Roots of Quadratic Equations. A real number x will be called a solution or a root if it satisfies the equation, meaning . It is easy to see that the roots
are exactly the x-intercepts of the quadratic function , that is the
intersection between the graph of the quadratic function with the
x-axis.</span>

As written, the denominator in both fractions is x, so the only restriction on the domain is ... x ≠ 0.

which is undefined when x = 4 or x = -2.
The domain is all real numbers except -2 and 4.
