Let'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
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
