Which are the roots of the quadratic function f(q) = q2 – 125? Select two options.

q = 55 StartRoot 5 EndRoot
q = -5Negative 5 StartRoot 5 Endroot
q = 33 StartRoot 5 Endroot
q = -3Negative 3 StartRoot 5 EndRoot
q = 2525 StartRoot 5 EndRoot

and

Step-by-step explanation:

We want to find roots of the function: . The roots are the numbers that make the function f(q) = 0. So set the expression equal to 0:

Add 125 to both sides:

Square root both sides:

+/- = +/- = +/-

So, the answers are and . (Sorry, I can't tell what the answer choices are)

Hope this helps!

q = 5 startroot 5 endroot

q = Negative 5 startroot 5 endroot

Step-by-step explanation:

q² - 125 = 0

q² = 125

q = +/- sqrt(125)

q = +/- 5sqrt(5)
