I'll help you on the last one. The other ones, you just plug into the quadratic formula which is very easy. x^2 +4x +3 = 0 (x+1)(x+3) = 0 x can equal -1, and x can equal -3 in order the eqn to equal zero. Try plugging in the numbers to see for yourself.

You've got a polynomial in the form of ax^2 +bx +c. Here's the quadratic formula: http://0.tqn.com/d/create/1/0/i/9/9/-/Quadratic.formula.jpg For the first one, a=1 b=10 c=-18 You can solve this, it's really easy! Just plug the numbers in.

@Rohangrr I'm very interested in helping people who want to know HOW to do the problem and giving them a thorough explanation on how to do a problem b/c I've been there. I know what it's like to have a teacher who barely touches on how to do a problem and then sets you free to do the homework even though you have almost no clue of what's going on. I guess you can say that I'm more interested in teaching the person to fish instead of handing it to them. I just want people to get value in my explanation and find it useful for the longterm. All I ask is that they are just as interested in learning the process as I am in explaining it. I trust that Erika was, but some people on here just want to pass their class and end up going into higher level maths with no clue of what's going on.
