How do you simplify #-6(-3-2x)-8x#?

Answer 1

Genesis Allen

#4x+18#

Multiply everything inside the brackets by #(-6)#

Keep in mind that a "minus" times a "minus" equals a "plus."

#+18+12x-8x" " =" " 18+4x#

This would normally be written as #4x+18#

To simplify the expression (-6(-3-2x)-8x), distribute the (-6) inside the parentheses:

[ -6(-3-2x) = 18 + 12x ]

Then, distribute the (-6) to ( -8x ):

[ -6(-3-2x)-8x = 18 + 12x - 8x ]

Finally, combine like terms:

[ 18 + 12x - 8x = 18 + 4x ]

So, the simplified expression is ( 18 + 4x ).

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.
