Question

Define cubic polynomial with two example of each.

Answer 1

A cubic polynomial is a polynomial of degree 3. A univariate cubic polynomial has the form f(x) = a3x³+a2x²+a1x+a0 .
An equation involving a cubic polynomial is called a cubic equation. A closed-form solution known as the cubic formula exists for the solutions of an arbitrary cubic equation.

Answer 2

A cubic polynomial is of form ax³+ bx²+cx + d
Also if Alfa , beta and gamma are it's zeroes then,
x³-(Alfa + beta + gama )x²+(alfa.beta +beta.gama.+gama.alfa)x-alfa.beta .gama
The dot(.) Represent multiplication
