This shoud be easy for some of you math buffs out there but im kind of new with
this math stuff..... well anyway. this math software i bought explains Quadratic Equations as so........

Ax2 + Bx + C = 0
where A = 1, B = 5, C = 6

then they say multiply AC and find the factors of the product.... so 2 + 3 = 5 = B

ok so now they have X2 + 2x + 3x + 6 = 0
ok fine but next it get confusing...

X(X+2)+ 3(X + 2) = 0 why is this broken up as so.

then they goto (X + 2) (X + 3) = 0
then finaly X = -2 or X = -3

1.) Is it normal to have two answers for a Quadratic Equation?

2.) How does (X + 2) (X + 3) = 0 equate to X = -2 or X = -3 ?

3.) Is there a less confusing way to do this???

thanks all.............
