Answer 2

Answer:

=> 13

Step-by-step explanation:

Given that:-

$z^2-2z+10$

The value of z is given as $-1$,

To find the value of the expression,

Now, plug the value of z as $-1$ in the equation:

As we have,

=> $z^2-2z+10$

=> $(-1)^2-2(-1)+10$

By simplifying it further, we get

=> $1-(-2)+10$

=> 13

Hence, the required solution is 13.
