Answer 2

The value of $4x+x-2x^{2} +x-1$  is  $-9$

Step-by-step explanation:

Given polynomial equation;

$4x+x-2x^{2} +x-1$ when $x=-1$

Let,

$p(x)=4x+x-2x^{2} +x-1$

In above equation plug $x=-1$,

$p(-1)=(4\times -1)+(-1)-2(-1)^{2}+( -1)-1$

$p(-1)=-4-1-2-1-1$

$p(-1)=-9$

Therefore the value of $4x+x-2x^{2} +x-1$  is  $-9$
