phi · Answer

It looks like you need to use the quadratic formula http://www.purplemath.com/modules/quadform.htm or use "completing the square"

phi · Answer

Have you learned either of these ?

anonymous · Answer

Yes but I have not used them in a while...

if you more problems like this, I would watch the video, because once you learn it, the problems go quickly.

anonymous · Answer

I have watched that video before.

phi · Answer

ok, can you say what is a, b, and c in 
x^2+5x+3=0

phi · Answer

if you don't know, watch the first 3 minutes again.

anonymous · Answer

$$a=x^2, b=5x, c=3$$

phi · Answer

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
