Help me solve? I'm not even sure where to begin... x^2+5x+3=0
It looks like you need to use the quadratic formula http://www.purplemath.com/modules/quadform.htm or use "completing the square"
Have you learned either of these ?
Yes but I have not used them in a while...
this video shows how http://www.khanacademy.org/math/algebra/quadratics/quadratic_formula/v/using-the-quadratic-formula
if you more problems like this, I would watch the video, because once you learn it, the problems go quickly.
I have watched that video before.
ok, can you say what is a, b, and c in x^2+5x+3=0
if you don't know, watch the first 3 minutes again.
close, but a , b and c are only the numbers, not the letters a=1 (the number in front of x^2 is 1 if you don't see a number) b=5 c=3
Oh, you are a life saver! Thank you so much :)
