Question

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

Answer 1

Answer:

The given options are not roots of q(x)

Step-by-step explanation:

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

To find the roots of the given quadratic equation

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

$0= q^2-125$

Add 125 on both sides

$125= q^2$

take square root on both sides

$q=+-5\sqrt{5}$

$q=+5\sqrt{5}$  and  $q=-5\sqrt{5}$

The given options are not roots of q(x)

Answer 2

Answer:

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