# How do you evaluate -6( - 2x ) - 4( - 6x )?

May 10, 2018

$36 x$

#### Explanation:

To solve, all you have to do is simplify.

Let's start piece by piece by looking at the coefficients of the numbers in the parenthesis,

which are $- 6$ and $- 4$ in $- 6 \left(- 2 x\right) \cdot - 4 \left(- 6 x\right)$

We'll distribute the coefficients, aka multiplying the $- 6$ with the $\left(- 2 x\right)$ and the $- 4$ with the $\left(- 6 x\right)$:

• $- 6 \cdot \left(- 2 x\right) = 12 x$
• $- 4 \cdot \left(- 6 x\right) = 24 x$

You only multiply the coefficients together, you leave x alone because it's an unknown variable.
Multiplying two negatives together leaves you with a positive answer.

Keep simplifying by combining like terms: $12 x + 24 x$

Which equals your answer, $36 x$.
