We can't help you if you don't tell us enough about what you are trying to do.  Are you supposed to factor these, solve them with the quadratic formula, what?  What have you tried doing so far?

anonymous · Answer

if you're factoring, then its
(w+11)(w+7)=0
so your final answer is 
w=-11, -7

anonymous · Answer

for the first one at least... Is this for virtual school?

anonymous · Answer

Like factoring trinomials ? 
Ex: 
6x^2 + 5x + 1 = 6x^2 + 3x + 2x+ 1
                       = (3x+1) (2x+1) 
Idk :/

anonymous · Answer

yeah, the first one factors... I haven't gotten to the others yet but they look like they all factor. #8 is actually a difference of squares so that ones really easy. what's the lesson supposed to be?
