question: Factor.
-12n-20
options:
a.) -4(3n-5)
b.) 4(3n+5)
c.) -4(3n+5)
d.) 4(3n-5)
When in doubt....just look at the answers...b and d would produce positive first terms....but the given problem has a negative first term.....
So...it appears it's a two-horse race....
Expand each remaining one and see what happens....
