sorry
at last it is x=-1

Answer 1

Answer :

The required answer is - 9

Step-by-step explanation :

Given equation ;

4x + x - 2x² + x - 1

Rearranging the equation,

-2x² + 6x - 1

Now, putting the value of x = - 1, we get ;

-2 ( - 1 )² + 6 ( - 1 ) - 1

⇒ - 2 - 6 - 1

⇒ - 9

Hence, the required answer is - 9.

Answer 2

4x+x-2x2+x-1 sub x=-1
4(-1)+-1-2(-1)2+-1-1
-4-1-2-1-1
-9
