Question

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

Answer 1

The statement is incorrect.
As all the terms have same variable $x$ to the power of $1$ on L.H.S, it should also have the variable $x$ to the power of $1$ on R.H.S, but not $x$ to the power of $2$ (or) $x^2$

Therefore the correct statement is
$3x+2x=5x$
