Answer:
[tex]x = 10 + \sqrt{90} [/tex]
Step-by-step explanation:
I think you meant [tex](x-10)^2 + 10 = 100[/tex] so I'm going to solve that.
here are the steps to solve this equation:
[tex](x-10)^2 + 10 = 100[/tex]
[tex](x-10)^2 = 90[/tex]
[tex]x-10 = \sqrt{90} [/tex]
[tex]x = 10 + \sqrt{90} [/tex]
