Answer:

The roots of the quadratic function is 5,-5.

Step-by-step explanation:

Given : Function [tex]f(q)=q^2-125[/tex]

To find : The roots of the quadratic function?

Solution :

Step 1 - Write the function as equating to zero to find roots

[tex]q^2-125=0[/tex]

Step 2 - Add 125 both side,

[tex]q^2-125+125=125[/tex]

[tex]q^2=125[/tex]

Step 3 - Taking the root both side,

[tex]\sqrt{q^2}=\sqrt{125}[/tex]

[tex]q=\pm5[/tex]

Therefore, The roots of the quadratic function is 5,-5.
