Random Indentation In my code

Question

Here is my COde:

\documentclass[12pt,fleqn]{article}
\usepackage[margin = 0.25in, letterpaper]{geometry}
\usepackage{amsmath, amssymb}
\usepackage{textcomp}
\usepackage{framed}

\usepackage{multicol}
\begin{document}
\begin{framed}
    \section[short]{Functions and Algebra}
    \textbf{POLYNOMIALS}\
    For (p(x)~|~ n~is~the~degree~of~p(x);)\
    (p(x) = a_{0}x^0 + a_{1}x + a_{2}x^2 ... a_{n}a^n )\
    With (p(x)) having (n) number of (zeros(z), complex ~ or ~ real), can be factored, \
    (p(x)=(x-z_{1})(x-z_{2})...(x-z_{n}))
    \begin{multicols}{2}
        \begin{framed}
            \begin{center}
                Common Factoring Formulae: \
                (a^2 - b^2 = (a+b)(a-b))\
                (a^3 \pm b^3 = (a-b)(a^2 + b^2 \mp ab))
            \end{center}
        \end{framed}
        \columnbreak
        \begin{framed}
            \begin{center}

                ((a \pm b)^3 = a^3 \pm 3a^2b + 3ab^2 + b^2)
            \end{center}
        \end{framed}
    \end{multicols}

\end{framed}
\end{document}

There seems to be a random indentation in line 37; \textbf{FUNCTIONS}\\

The error code is Underfull \hbox (badness 10000)LaTeX

I searched for the error and fixed previous issues of this same error code, but I can't seem to get this exact one fixed. Here is what My output looks like. I'll highlight the random indentation:

Please help me, I am a beginner LaTeX programmer. Sorry if this question was asked already.

Underfull \hbox (badness 10000) is because you have misplaced \\ at the end of a paragraph, delete all of those.

The red arrow is not a "random indent" it is a normal start of paragraph indent, you should use a section heading such as

\subsection*{FUNCTIONS}

not \textbf

POLOYNOMIALS should also be \subsection* the indent is suppressed in that case as it is the first paragraph after the \section{Functions and Algebra} heading.

So sorry for my stupid mistakes, If I don't put the \ in my code, I won't have the new line. Is there any way for me to do that without \?
I'm a bare beginner, so do you have any websites that I can refer to for code commands? Thanks, A LOT. I will make sure to not make this mistake again

@grade12boi Simple rule: *don't* use \\ to end lines in normal text. A paragraph is ended by leaving a blank line in the input file. – egreg Dec 22 '23 at 20:35
if you marked it as a section heading you would get a newline without \\ and for ending normal paragraphs just use a blank line in the source. You should almost never have \\ except to mark the ends of table rows. @grade12boi – David Carlisle Dec 22 '23 at 20:37
