The polynomial expression is .
This is not a perfect square trinomial. \ \
\The trinomial compare to general trinomial expression: , So a = 1, b =
5, c = 6.
To find two numbers with a sum of 5 and a product of
.
This trinomial list of the factors of 6, and look for the pair of factors is a sum of 5.

The correct factors are 2 and
3.
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 .
Group terms with common factors.
\Combine like terms using distributive property: ac bc = (a
b)c.
Check:
\To check the solution by multiply the two factors.
\ (Using FOIL method)
Product of two different sings is a negative.
\Product of two same sings is a positive.
\Combine like terms using distributive property: ac bc = (a
b)c.
The solution is "true".
The solution is .
