The trinomial expression is
.
The trinomial compare to general trinomial expression:
, So x = a, b = 27, c = 72.
To find two numbers with a sum of 27 and a product of 72.
\This trinomial list of the factors of 72, and look for the pair of factors is a sum of 27.
\| Factors of 72 | \Sum of factor | \
| \
8, 9 \
| \
\
17 \27 \ | \
The correct factors are 3 and 24.
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).

Check:
\To check the solution by multiply the two factors.
\
(Using FOIL method)

Combine like terms using distributive property: ac + bc = (a + b)c.
\

The solution is "true".
The solution is
.
