Answer 2

Answer:

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

Step-by-step explanation:

Given -

$x=-1$

We have to find out the value of $x^{2} -x+2$

Put the given value of x in the equation

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

When ( - ) multiplied by ( - ) is equal to ( + )

S0,

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

Square means multiplying the given number with itself twice.

The square of negative number is always positive.

$(-1) \times (-1) = 1$

$=1+1+2$

$=2+2\\=4$

Hence,

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