equation is an equation is a second degree equation whose
general form is Ax^2=Bx+C=0. For example, 2x^2+8x+6=0. Note that
there can be equations not in this general form, but they can be
put into this general form. For example, 2x^2+8x+9=3 can be put
into the general form by simply subtracting 3 from both sides.
Once the equation is in general form, it can be solved by one of
3 methods. The first is factoring. Notice that the above
equation can be factored as (2x+2)(X+3)=0. Since one of these
factors must equal 0 for the equa
