Question

Alpha ,beta and gamma are zeroes of cubic polynomial x^3-12+44x+c ,if appa ,beta,gamma are in Ap ,find valu of c? In this Question ,what is A.P or its fullform

Answer 1

Answer:

SP = arithmetic progression

Step-by-step explanation:

for a cubic polynomial

alfa+beta+ gamma= -b/a

alfa×beta×gamma= -d/a

alfa×beta + beta×gamma+ gamma×alfa = c/a

given polynomial

x³-12+44x+c

= x³ + 44x +( c-12)

solution is attached

c=12

AP= arithmetic progression
