Question

Which polynomial is a cubic trinomial?

2x^2 - 4x + 6
2x^3 - 2x^2 -4x
2x^3 + 6
2x^3 - 2x^2

Answer 1

`2 {x}^(3) - 2 {x}^(2) - 4x`

Step-by-step explanation

A cubic polynomial should have degree 3 .

A trinomial is a simplified polynomial with 3 terms.

A cubic polynomial will therefore have 3 terms with degree 3.

The correct choice is

`2 {x}^(3) - 2 {x}^(2) - 4x`
