3 is the solution to $$x+1=4$$
You could just leave this as unformatted math. But it's prettier if you enter it using LaTeX.
$$3$$ is the solution to $$x+1=4$$
2 is a solution to x<5/2

The greater-than sign and the less-than sign are used in HTML element declarations.

To be safe, rather than typing them, use \lt and \gt.

$$2$$ is a solution to $$x\lt\frac{5}{2}$$
3x^2-15x-18 = 3(x^2-5x-6)            = 3(x + 1)(x - 6)

For multi-line expressions, use the aligned environment.

The & character marks where alignment happens.

The \\ marks where rows end.

Using \left( and \right), instead of just ( and ), will make the parentheses grow to the appropriate height.

Note the extra braces around the 3 and the \left(...\right) expression. These just make the spacing nicer.

\begin{aligned}3x^2-15x-18 &={3}{\left(x^2-5x-6\right)}\\ &=3(x+1)(x-6)\end{aligned}
