A Bernoulli differential equation is one of the form dxdy+P(x)y=Q(x)yn Observe that, if n=0 or 1, the Bernoulli equation is line
ar. For other values of n, the substitution u=y1−n transforms the Bernoulli equation into the linear equation dxdu+(1−n)P(x)u=(1−n)Q(x) Use an appropriate substitution to solve the equation xy+y=4xy2
