Homework Statement
Prove that if x is a real number then 2x2-3=0
Homework Equations
The Attempt at a Solution
Well I think this proof is OK but it seems very to the point, please tell me if there is any fallacy in my reasoning.
2x2-3=0
2x2=3
but 2x2 is even, while 3 is odd
Hence x must be irrational for all real x.
