How do you simplify #-6x+4(-x-3)#?

Answer 1

See the entire simplification process below:

First, expand the terms within the parenthesis by multiplying each term within the parenthesis by the term outside the parenthesis:

#-6x + color(red)(4)(-x - 3) ->#

#-6x + (color(red)(4) xx -x) + (color(red)(4) xx -3) ->#

#-6x + (-4x) + (-12) ->#

#-6x - 4x - 12 ->#

#(-6 - 4)x - 12 ->#

#-10x - 12#

To simplify -6x + 4(-x - 3), we can distribute the 4 to both terms inside the parentheses:

-6x + 4(-x - 3) = -6x + (-4x) + (-12)

Combining like terms, we have:

-6x - 4x - 12 = -10x - 12

Therefore, the simplified form of -6x + 4(-x - 3) is -10x - 12.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
