# Writing empty set as union of basis elements for a topology.
In Munkres’ topology, there are two instances where we would have to represent the empty set as a union of sets.
First, we have a lemma that says if $$X$$ is a set; and $$\mathcal{B}$$ is a basis for a topology $$\tau$$ on $$X$$, then $$\tau$$ is equal to... | HuggingFaceTB/finemath | |

# How do you combine -4( - 8x - 8) + 12x?
Feb 5, 2018
See below...
#### Explanation:
First we must expand the brackets.
$\therefore - 4 \left(- 8 x - 8\right) = 32 x + 32$
This gives the expression $32 x + 32 + 12 x$
Now we collect the like terms.
$\therefore 32 x + 32 + 12 x = 44 x + 32$
