Question

I am suppose to determine whether the statement below is true or false, and explain or support me answer by providing an example.

For all real numbers a and b, 2a b = a2 + b2

Answer 1

I need help bad

Answer 2

\[2ab=a^2+b^2\]??

Answer 3

yes

Answer 4

almost anything would be a counter example
you could try \(a=b=10\) and see that
\[2\times 10\times 10\neq 10^2+10^2\] make up any numbers you choose, it is unlikely to work
