Which are the roots of the quadratic function f(q) = q^2 - 125? Select two options.
q= 5/5
q = -5/5
q=375
q=-3/5
q = 2575

None of the options are correct

Step-by-step explanation:

Given

Required

The roots of the function

Since the function is a quadratic function; to get the roots of the function, f(q) must be equal to 0

becomes

Make the subject of formula

Rearrange

Take square roots of both sides

Expand the square root of 125

q = ±5

Split into 2

or

or

Hence, the roots of the quadratic function are or
