1. Sum of the zeros of the cubic polynomialP(x) = 3x - 5x2 - 11x-3 is

1.	1. Sum of the zeros of the cubic polynomialP(x) = 3x - 5x2 - 11x-3 is [HSLC'15](a) 5(b) 11 (c) 3(d)whh
Answer» f(x)=3(3)^3-5(3)^2-11(3)-3=3(27)-5(9)-33-3=81-45-33-3=81-81=0 (d) option is correct -b/a P(x)= 3x^3-5x-11x-3sum of zeros= -b/a= -(-5)/3 = 5/3option D is right option D is the correct answer Sum of zero=-b/a=-(-5)/3=5/3

Answer»

f(x)=3(3)^3-5(3)^2-11(3)-3=3(27)-5(9)-33-3=81-45-33-3=81-81=0

(d) option is correct -b/a

P(x)= 3x^3-5x-11x-3sum of zeros= -b/a= -(-5)/3 = 5/3option D is right

option D is the correct answer

Sum of zero=-b/a=-(-5)/3=5/3
