Question

Which are the roots of the quadratic function f(b) = b2 - 75? Select two options

Answer 1

The given quadratic function is b^2 - 75.

The roots can be obtained by equating the given function with zero.

so, b^2 - 75 = 0

=> b^2 = 75

=> b = ± 5√3

Therefore the roots of given quadratic function are 5√3 and -5√3.
