Question

Which are the roots of the quadratic function f(q) = q2 – 125? Select two options.

Answer 1

Answer:

What are the options?

Step-by-step explanation:

Answer 2

Answer:

±11.18

Step-by-step explanation:

the function is:

$f(q)=q^2-125$

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

$q^2-125=0$

solving for $q$:

$q^2=125\\q=\sqrt{125}$

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

$q=$±$\sqrt{125}$ ≈ ±11.18

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