Error With Inequality

Question

I typed the following and get an error. Help would be appreciated it. $x^{2}\lneq x$ It states undefined control sequence.

you need to have \usepackage{amssymb} in your preamble. that's where the name is defined; the symbol is included in the amsfonts. — barbara beeton, May 09 '16 at 01:53
Welcome! It is obvious in this case, but always include the exact error message - which control sequence is undefined? — cfr, May 09 '16 at 01:58
