If m1and m2 are the roots of the auxiliary equation of the given linea...
The given linear differential equation of second order with constant coefficients can be written as:

a(d^2y/dx^2) + b(dy/dx) + cy = 0

where a, b, and c are constants.

The auxiliary equation for this differential equation is obtained by assuming a solution of the form y = e^(mx), where m is a constant. Substituting this into the differential equation, we get:

a(m^2e^(mx)) + b(me^(mx)) + ce^(mx) = 0

Simplifying this equation gives us the auxiliary equation:

am^2 + bm + c = 0

This is a quadratic equation in m, and its roots m1 and m2 are the solutions to the auxiliary equation.

Now let's go through each option to determine which one is correct:

a) m1 and m2 are always real and distinct:
This is not always true. The roots of the auxiliary equation can be real and distinct, but they can also be complex or equal. So option a is incorrect.

b) m1 and m2 are always complex:
This is also not always true. The roots of the auxiliary equation can be real or complex. So option b is incorrect.

c) m1 and m2 both may be complex and equal:
This is true. The roots of the auxiliary equation can be complex and equal. For example, if the quadratic equation has a discriminant of zero, then the roots will be complex and equal. So option c is correct.

d) m1 and m2 both may be real and equal, real and distinct, or complex:
This is also true. The roots of the auxiliary equation can be real and equal, real and distinct, or complex. So option d is correct.

In conclusion, the correct answer is option d. The roots m1 and m2 of the auxiliary equation can be real and equal, real and distinct, or complex.
