Text Formatting ⇒ Enumerate and Equation

[limus]

Hello, I'm new to latex. I want to use latex in my website (wordpress based). Is there any way to create such equation? I need the equation starts right after numbering and align the = sign

Note: the equal = in number 1 and 2 doesn't need to be in same align

Thanks in advance

Hi Limus,

welcome to the forum!

Sure, what's the specific question? Is it about aligning the equal signs of the first equation? Or about typing all code? If you show is the code you have, we can help improving it and give working code.

Do you use a LaTeX Wordpress plugin? Btw. you can use a LaTeX compiler right on your wordpress website, such as on LaTeX-Cookbook.net.

I use Simple Mathjax since it works best with Gutenberg Block. Sorry, I forgot to mention that I wrote the equation in Ms. Word.

I tried this code

\begin{enumerate}
\item \begin{flalign*}f(x)g(x)&=\left(2x^2+3x-4\right)\left(3x^2-2x\right)&\\
&=6x^4-4x^3+9x^3-6x^2-12x^2+8x&\\
&=6x^4+5x^3-18x^2+8x&\end{flalign*}
\item $f(x)g(x)=\left(2x^2+3x-4\right)\left(3x^2-2x\right)\\
=6x^4-4x^3+9x^3-6x^2-12x^2+8x\\
=6x^4+5x^3-18x^2+8x\\D_{f\times g}=D_{f}+D_{g}=2+2=4$
\end{enumerate}
I want the equal sign (=) align like number 1 and the equation start after the numbering like number 2, is there any way to handle it? Again, thank you for your response

Please try to provide a minimal working example.

The aligned environment could fit these requirements.

Code: Select all

\documentclass{article}
\usepackage{mathtools}% loads amsmath

\begin{document}
\begin{enumerate}
\item $\begin{aligned}[t] 
f(x)g(x)&=\left(2x^2+3x-4\right)\left(3x^2-2x\right)\\
        &=6x^4-4x^3+9x^3-6x^2-12x^2+8x\\
        &=6x^4+5x^3-18x^2+8x
\end{aligned}$
\end{enumerate}
\end{document}
