Binomial (x – 6) and trinomial (–2x2 + x + 9) are the factors of which of the following polynomials?

Respuesta :

Answer:

The polynomial is -2x³ + 13x² + 3x - 54.

Step-by-step explanation:

The binomial expression is: (x - 6)

The trinomial expression is: (-2x² + x + 9)

Multiply the two expressions to determine the resulting polynomial as follows:

[tex](x-6)(-2x^{2}+x+9)=x(-2x^{2}+x+9)-6(-2x^{2}+x+9)[/tex]

                                   [tex]=-2x^{3}+x^{2}+9x+12x^{2}-6x-54\\=-2x^{3}+13x^{2}+3x-54[/tex]

Thus, the polynomial is -2x³ + 13x² + 3x - 54.
