Answer:

±11.18

Explanation:

the function is:

f(q)=q^2-125

and to find the roots we need to find which values of
makes the function result in zero:

q^2-125=0

solving for
:

$q^2=125\\q=√(125)$

A square root has two solutions, one positive and one negative, so the solutions are:

±
√(125) ≈ ±11.18

the roots of the quadratic equation are +11.18 and -11.18
