This is a linear constant coefficient homogeneous ODE, so: First solve the charateristic equation: The roots of this are (with multiplicity 2) and , and your notes should tell you where to go from here.

therefore the r=1(with multiplicity 2) is actually a double root not a distinct root right?

some help on solving this homogeneous ODE pls.. y''''+4k^4y=0 where k is non zero constant
