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.
