Second order linear homogeneous differential equation with constant coefficients, ODE has a form of,

From here we assume that for any equation of that form has a solution of the form,

Now the equation looks like this,

Now simplify to,

You can solve the simplified equation using quadratic equation since,

Using the QE we result with,

So,

For two real roots the general solution takes the form of,

Or simply,

Hope this helps.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
