What is x squared plus x squared?

Solution:

x squared equals x multiplied by itself.

In algebra, x multiplied by x can be written as (x) × (x) or x².

So, x squared = x².

Then, x squared plus x squared = x² + x² = 2x².

Thus, x squared plus x squared is x² + x² = 2x².

What is x squared plus x squared?

Summary:

x squared plus x squared is 2x².
