alpha, beta & gamma are the zeroes of cubic polynomial P(x) = ax^3 + bx^2 + cx + d, (a ≠ 0) then product of their zeroes [alpha .
Similarly, How do you find the cubic polynomial? The cubic polynomial formula is in the general form of ax3 + bx2 + cx + d and the formula for the solution of the cubic equation is ax3 + bx2 + cx + d = 0.
What is alpha plus beta plus gamma? α + β + γ = -b/a i.e sum of roots = -b/a. α β + β γ + αγ = c/a i.e products of roots taken 2 at a time = c/a.
How do you calculate alpha beta gamma in cubic equations? We are given that α,β&γ are the zeroes of cubic polynomial P(x)=ax3+bx3+cx+d,(a≠0) then product of their zeroes [α. β.
Secondly How do you find a cubic equation when given zeros? Use the sum of zeroes, product of the zeroes and sum of the product of the zero’s formula. Zeroes of the cubic polynomials are α,β,γ. Here α is equal to 3 ,β is equal to 5 and γ is equal to -2. In the cubic polynomial the coefficient of x3 is a, coefficient of x2 is b, coefficient of x is c and the consent term is d.
How do you solve a class 10 cubic equation?
Complete step-by-step answer: We start the solution by getting one root of the equation [{{x}^{3}}-23{{x}^{2}}+142x-120=0] by hit and trial method. Next step is to solve the equation obtained in (i) which is a quadratic equation, to get the remaining two roots.
then How do you find a cubic polynomial whose zeros are given? Answer Expert Verified
- Answer:
- Step-by-step explanation:
- Sum of roots = α + β + γ
- Sum of products of roots = αβ + βγ + γα
- Product of roots = αβγ
- Now, cubic polynomial is given by –
- = x³ + 6x² + 11x + 6.

How do you write the roots of a cubic equation? Approach: Let the root of the cubic equation (ax3 + bx2 + cx + d = 0) be A, B and C. Then the given cubic equation can be represents as: ax3 + bx2 + cx + d = x3 – (A + B + C)x2 + (AB + BC +CA)x + A*B*C = 0. Therefore using the above relation find the value of X, Y, and Z and form the required cubic equation.
