Question

if one of the zeroes of cubic polynomial 2ax^3+3x^2+5x+2 is zero then find the product of the other two zeroes

Answer 1

Answer:

We generally know that the sum of product of roots of a cubic equation is given by c/a

Given one root is 0

Let the other roots be α,β

So,

αβ + β(0) + (0)α = c/a

αβ = c/a

Hence the product of other two roots is c/a

Answer 2

Answer:

(b) Let p(x) =ax3 + bx2 + cx + d

(b) Let p(x) =ax3 + bx2 + cx + dGiven that, one of the zeroes of the cubic polynomial p(x) is zero.

(b) Let p(x) =ax3 + bx2 + cx + dGiven that, one of the zeroes of the cubic polynomial p(x) is zero.Let α, β and γ are the zeroes of cubic polynomial p(x), where a = 0.

(b) Let p(x) =ax3 + bx2 + cx + dGiven that, one of the zeroes of the cubic polynomial p(x) is zero.Let α, β and γ are the zeroes of cubic polynomial p(x), where a = 0.We know that,
