Question

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

Answer 1

q^2 - 125 = 0
q^2 = 125
q = ±√125 = ±5√5

Answer 2

The roots of the quadratic function f(q) = q^2 - 125 are:

q = 11.18 StartRoot 5 EndRoot
q = -11.18Negative 11.18

Answer 3

Apologies for the mistake in the previous responses. You are correct.

The correct roots of the quadratic function f(q) = q^2 - 125 are:

q = 5√5
q = -5√5
