(10 points) A Bernoull difterential equation is one of the form dxdy+P(x)y=Q(x)y Ooserve that, if n=0 or 1 , the Bemoull equation is ineac. For other values of n, the substatuion u=y1 transtarns the Bernouil equation into the Iiroar equation dxdu+(1n)P(x)u=(1n)Q(x) Use an appropriate substhution to solve the equation yx27y=x7y2 and fnd the solition that batisies y(1)=1. y(x)=.
