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

The given options are not roots of q(x)

Step-by-step explanation:

To find the roots of the given quadratic equation

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

Add 125 on both sides

take square root on both sides

 and  

The given options are not roots of q(x)

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
