# How do you write the phrase as a variable expression: the product of -6 and the sum of a number and -1?

$- 6 \left(x - 1\right) \mathmr{and} - 6$ x$\left(x - 1\right)$

#### Explanation:

You can consider "the sum of a number and -1" as a single entity.
So the question is asking the product of -6 and sum of a number and -1

$\implies - 6$ x (the sum of a number and -1)

Since, we don't know what the number is, we assume it as a variable (say x).

$\implies - 6$ x $\left(x + \left(- 1\right)\right)$
$\implies - 6$ x $\left(x - 1\right)$
Or, $- 6 \left(x - 1\right)$
