The trinomial expression is .
Rewrite the trinomial expression .
The trinomial compare to general trinomial expression: ,So x = w, b = 6, c =
72.
To find two numbers with a sum of 6 and a product of 72.
This trinomial list of the factors of 72, and look for the pair of factors is a sum of 6.

The correct factors are 6 and 12.
To factor trinomials of the form , find two integers, m and n, with a sum equal to b and a product equal to c.
Then write as (x + m)(x + n).
