Question

If one of the zeros of the cubic polynomial x cube + a x square + bx + c is -1 then find the product of the other two zeros

Answer 1

Answer:

Step-by-step explanation:

let alpha, beta and gamma be the zeroes of the cubic polynomial

x^3 +ax^2 + bx + c, then

alpha× beta×gamma = - c

if alpha = - 1, then

(- 1)×beta×gamma = - c

beta×gamma = c.
