To factor a trinomial means to write the trinomial as a product of two factors. It is the reverse of expansion (FOIL).
Example :
In order to factor the trinomial,
we need to find two constants p and q such that:
Now, if we expand the RHS we will get:
Comparing coefficients, we get:
So, b = p + q and c = pq.
In other words, we need to find two constants p and q such that their sum p + q = b and their product pq = c.
