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 .
