Question

which of the following is equal to 1 ? tu degree +3 degree*4 degree b) 2 degree*3 degree*4 degree c) (3 degree - 2)*4 d) (3 degree-2 degree) *(3 degree+2 degree)​

Answer 1

Answer:

Correct option is

C

P(x).P′′′(x)

y2=P(x)

P(x) is a polynomial of degree 3

y2=P(x)

2ydxdy=P′(x)

2ydx2d2y+2(dxdy)2=P′′(x)

dx2d2y=2yP′′(x)−2[2yP′(x)]2

y3dx2d2y=2yy3P′′(x)−
