Solving a Quadratic

Yesterday we learned that taking each factor and setting it equal to zero and solving allows us to find the x-intercepts of the graphs.
 
For example,
 
f(x) = x^2+6x+8 factors to f(x) = (x+4)(x+2).  
If we understand that f(x) and y are synonymous and that y = 0 along the x-axis, I have 0 = (x+4)(x+2).
Knowing that multiplying and getting an answer of a 0 means that I have multiplied by a 0, then I can set each factor = 0 and solve for x.....x+4 = 0, therefore x = -4.  Likewise, x+2 = 0, therefore x = -2.  These two give us the points (-2,0) and (-4,0) giving me the x-intercepts for the graphs.  This is called "Solving a Quadratic".
