Find and correct errors of the following mathematical expressions: 3x + 2x = 5x²

The statement is incorrect. As all the terms have the same variable x to the power of 1 on the L.H.S, it should also have the variable x to the power of 1 on the R.H.S, but not x to the power of 2 (or) x². Therefore the correct statement is 3x + 2x = 5x
