Problem 7E

In Problems 1–14, find at least the first three nonzero terms in the series expansion about x = 0 for a general solution to the given equation for x > 0. (These are the same equations as in Problems 19–32 of Exercises 8.6.)

Common factor here is 7y, since both can be divided by 7 and y, so factor out 7y.) 7y (y + 4) = 0 (By the Zero Factor Property, we know that for this product to equal zero, then at least one of the two factors must equal 0, as well. To determine the other solution of the
