**Yolonda**, Thursday, November 29, 2012 at 8:50pmLet's factor the trinomial x² + bx + c. We know that if b²-4c >= 0 then this trinomial has zeros and it can be factorized. It's zeros are

x1 = [ -b + √(b²-4c) ] / 2

and

x2 = [ -b - √(b²-4c) ] / 2.

So, we can factor it as

x² + bx + c = (x-x1)(x-x2).

In a case of trinomial ax² + bx + c we can factorize it as

ax² + bx + c = a(x² + b/a·x + c/a),

where the trinomial x² + b/a·x + c/a has the same form as x² + bx + c.
