Here's the question you clicked on:
npraval
by eliminating the constant C1 and C2, find the differential equation of the following family curve y=C1x + C2x^2
Derive with respect to x? But you're not allowed C1 and C2 in your final answer?
Alright, hacks since I don't actually get the question: Derive with respect to x. Derive with respect to x. Integrate. Done!
what will be the answer
\(C_2=\frac{y''}2\), \(C_1=y-y''x\)\[y=(y−y''x)x+\frac{y''}2\]Simplify and get an answer.
Sorry, but i'd like @npraval to find this mistake instead of you. :)
