Question

-3x² + 2x - 1
when x = -1
answer with full solution please ​

Answer 1

Answer:

The value of is -6 at x = -1

Step-by-step explanation:

Here we have been given the following polynomial:

$-3x^{2} +2x -1$

As in the question we have been given to find the value of the above-given polynomial at the value of x = -1

Now for this, we put x = -1 in the following polynomial as below:

$-3x^{2} +2x -1$

= $-3(-1)^{2} + 2(-1) -1$

= -3 -2 -1

= -6

Hence the value of the polynomial putting x = -1 is -6
