y = x2+4x+3
The parabola graph puts it as: x= -1, -3.
The equation didn't have negative numbers in it in the first place. So why does the graph make them negatives?
---------------

Find where y = 0:

(x+3)*(x+1) = 0
For the product to be 0, either x+3 = 0 or x+1 = 0
x+3 = 0
x = -3
-------
x+1 = 0
x = -1
