2x x2-4

It looks like you're trying to factor an expression or possibly solve an equation. The expression "2x x^2 - 4" can be written as:

\[ 2x \cdot (x^2 - 4) \]

The \( x^2 - 4 \) part is a difference of squares, which can be factored further:

\[ x^2 - 4 = (x - 2)(x + 2) \]

Putting it all together, we have:

\[ 2x(x^2 - 4) = 2x(x - 2)(x + 2) \]
