Answer 2

Answer:

=> 1000

Step-by-step explanation:

Given that:-

$z^2-3(z-10)$

To find:- The value of the expression.

As we have,

=> $z^2-3(z-10)$

Now, distribute the terms we get

=> $z^2-3z+30$

Now, plug the value of z as $10$ we get

=> $(10)^2-3(10)+30$

Simplifying it further, we get

=> 100 - 30 + 30

=> 1000

Hence, the required solution is 1000.
