Hi! I hope you are enjoying your day!
Let's evaluate this expression for x.
We are given that
[tex]\bold{x=10}[/tex]
All we have to do in order to solve this expression is plug in the value of x.
[tex]\bold{x^2-2(x+5)}\\[/tex]
[tex]\bold{x^2-2x-10}[/tex]
Now, plug in the value of x:
[tex]\bold{10^2-2(10)-10}[/tex]
10² is equal to 100:
[tex]\bold{100-20-10}[/tex]
[tex]\bold{100-30}[/tex]
And that is equal to
[tex]\boxed{\boxed{\bold{70}}}[/tex]
Hope everything is clear.
If you have any questions, please comment.
