Question

Factorisation of cubic polynomia (1 example)

Answer 1

Answer:

• There are no unfactorable cubic polynomials over the real numbers because every cubic must have a real root.

• Cubics such as x^3 + x + 1 that have an irrational real root cannot be factored into polynomials with integer or rational coefficients.

Hope it will be helpful :)

Answer 2

Answer: Cubic polynomials are polynomials of degree three. Examples include \begin{align*}x^3+8, x^3-4x^2+3x-5\end{align*}, and so on. Notice in these examples, the largest exponent for the variable is three (3). They are all cubics
