Correct answer is (a) a+b=-3Correct answer is (c) a + b + c =3

Q. Consider, $y^{3} + a y^{2} x^{3} + b y x^{6} - c x^{9} = 0, a, b, c \in R$ . If the possible values of $\frac{d ^{3} y}{d x ^{3}}$ are $- 6, 12$ and -18 , then

$a + b = - 3$

$b + c = - 6$

$a + b + c = 3$

$a + b + c = - 13$

Correct answer is (a) $a + b = - 3$ Correct answer is (c) $a + b + c = 3$

Q. Consider, y3+ay2x3+byx6−cx9=0,a,b,c∈R. If the possible values of dx3d3y​ are −6,12 and -18 , then

a+b=−3

b+c=−6

a+b+c=3

a+b+c=−13
