Exercise 78 Page 213

Be careful of negatives when distributing.

- 6x+24

Practice makes perfect

We will begin simplifying by distributing the -6 to the terms inside the parentheses.

- 6(x-4)

Distribute - 6

-6x-(- 6)4

MultNegNegOnePar

- a(- b)=a* b

- 6x+24

Since - 6x and 24 are not like terms, the expression cannot be simplified further.
