Which are the roots of the quadratic function f(q) = q2 – 125? Check all that apply. q = 5 q = –5 q = 3 q = –3 q = 25 q = –25

Respuesta :

Answer:

The given options are not roots of q(x)

Step-by-step explanation:

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

To find the roots of the given quadratic equation

we replace f(q) with 0  and solve for q

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

Add 125 on both sides

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

take square root on both sides

[tex]q=+-5\sqrt{5}[/tex]

[tex]q=+5\sqrt{5}[/tex]  and  [tex]q=-5\sqrt{5}[/tex]

The given options are not roots of q(x)

Answer:

q=5 sqrt 5 and q=-5 sqrt 5
