Answer 2

Answer:

Option (d)

– d/a

Note:

★ The general form of a cubic polynomial is given as ; ax³ + bx² + cx + d

★ If A , B , C are the zeros of the cubic polynomial ax³ + bx² + cx + d , then ;

• Sum of zeros = -b/a

=> A + B + C = -b/a

• Sum of products of zeros taking two at a time = c/a .

=> A•B + B•C + C•A = c/a

• Product of zeros = -d/a

=> A•B•C = -d/a

Solution:

Here,

The given cubic polynomial is ;

ax³ + bx² + cx + d

Here,

The product of it's zeros = -d/a

Hence,

The required answer is (-d/a) .
