Hi! I hope you are enjoying your day!

Let's evaluate this expression for x.

We are given that

$\bold{x=10}$

All we have to do in order to solve this expression is plug in the value of x.

$\bold{x^2-2(x+5)}\\$

$\bold{x^2-2x-10}$

Now, plug in the value of x:

$\bold{10^2-2(10)-10}$

10² is equal to 100:

$\bold{100-20-10}$

$\bold{100-30}$

And that is equal to

$\boxed{\boxed{\bold{70}}}$

Hope everything is clear.
