## anonymous 3 years ago 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?

2. anonymous

Alright, hacks since I don't actually get the question: Derive with respect to x. Derive with respect to x. Integrate. Done!

$$C_2=\frac{y''}2$$, $$C_1=y-y''x$$$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. :)

fair enough!
