# How do you factor -3x-4x?

$3 x - 4 x = \textcolor{red}{x \left(- 3 - 4\right)} \text{ or " color(red)((-7)(x))" or } \textcolor{red}{\left(7\right) \left(- x\right)}$
Extract either $\textcolor{b l u e}{x}$ or color(blue)(""(-x)) as a common factor of the terms $\left(- 3 x\right)$ and $\left(- 4 x\right)$
