Math & Science ⇒ Fractions

[Mini]

Hello,

In my latex document, I have the following code:

Code: Select all

\\ (a) \ GP \frac{x+2}{x-2} = \frac{5x-2}{x+2}
\\ x^2+4x+4=5x^2-12x+4
\\ 0=4x^2-16x
\\ x=0 \ or \ 4

But it comes out as attached. I know the first line is the problem. I just want an ordinary fraction ie. (x+2)/(x-2) = (5x-2)/(x+2)... how would I achieve this?

Also, the font size for fractions, when they do work (which is for only numbers and single termed algebraic expressions) the size of it becomes really small and hard to read. How would I make the font size remain the same as the rest of the document?

Thanks, I think I'm getting the hang of this

Are you not using math mode? You must be getting a bunch of errors. You can't write that kind of math outside of math mode.

Consider using something like:

Code: Select all

\documentclass[leqno]{article}
\usepackage{amsmath}

\begin{document}
  \begin{equation} \tag{a}
    \begin{split}
      \text{GP } \frac{x+2}{x-2} &= \frac{5x-2}{x+2} \\
      x^2+4x+4 &= 5x^2-12x+4 \\
      0 &= 4x^2-16x \\
      x &=0 \text{ or } 4
    \end{split}
  \end{equation}
\end{document}

Firstly, thank you. That's why I've been getting all these errors!

To clarify, I'm ONLY using LateX for maths. Thank you again!
