Answer 2

As per the data given in the question,

We have to determine the value of "x" in the above given expression when the value of "x = - 1".

As per data,

It is given that,

$x^2+2x+1$

So, for solving the value of expression we will put the value of "x" in above expression.

So, we will get,

$x^2+2x+1\\(-1)^2+(2\times -1)+1\\=>1-2+1\\=>0$

Hence, we will get value of the expression will be 0 if we put the value of " x = -1"  in the above given expression.

Actual question,

$x^2+2x+1$ find the value of this expression when x=-1
