Answer:
The solution set of the quadratic function
is
.
Step-by-step explanation:
Let be a second-order polynomial (quadratic function) is standard form and equalized to zero:

Its roots can be determined by the Quadratic Formula in terms of its polynomial coefficients, which states that:

Given that
,
and
, the roots of the polynomial are, respectively:




The solution set of the quadratic function
is
