Question: how to solve this equation?

this is the differential equation of second derivative. because i learn Maple not long. the equation name is 'eq5' > eq5:=D(D(x1))=(a1*fx1+a2*gx1)*D(x1)+(a1*fx2+a2*gx2)*D(x2)+(a1*fxt+a2*gxt); x1(t),in the file. if you interesting ,just download the file to help me to solve this problem. regards.
