which especially represents the complete factor form of [tex]2x^3 + {x}^{2} - 8x - 4[/tex]a. [tex](2x - 4)(2x + 1)[/tex]b.[tex](x - 2) ^{2} (2x - 1)[/tex]c.[tex](x - 2)(x + 2)(2x - 1)[/tex]d.[tex](x - 2)(x + 2)(2x + 1)[/tex]

Respuesta :

[tex]\begin{gathered} \text{ We will see that } \\ (x-2)(x+2)(2x+1)=2x^3+x^2-8x-4 \\ \\ \\ (x-2)(x+2)(2x+1)=(x^2-4)(2x+1) \\ =2x^3+x^2-8x-4 \\ \\ \text{ Thus the answer is d.} \end{gathered}[/tex]
