Question

What is (2x - 4) - (6x + 6)

Answer 1

-4x-10

The 6x + 6 becomes negative due to the negative sign before the parenthesis. You then subtract 6x and 6 from 2x and -4 to get -4x-10

Answer 2

Step-by-step explanation: (2x-4)-(6x+6)

= 2x -4 - 6x - 6 [ opening brackets]

= 2x-6x -4-6 [ bringing the same variables and numbers together]

= -4x-10

=2(2x-5)
