Find the first three nonzero terms, or as many as exist, in the series expansion about x= 0 for a general solution to the given equation for x>0. xy" + (1- x)y' - y= 0 The equation has a general solution in the form c, y, (x) + Cay2(x) where y, (x) is obtained from the root of the associated indicial equation with the largest real value. If the second solution has term with y, (x), then count that term as only one term. Y1 (x) = + ... and y2(x) = + ..
