The trinomial expression is .
The trinomial compare to general trinomial expression: , So a = 2, b =
11, c = 7.
To find two numbers with a sum of 11 and a product of
.
This trinomial list of the factors of 14, and look for the pair of factors is a sum of 11.
Factors of 14 | \Sum of factors | \
\
2, 6, 2 \2, 6 \ | \
\
8 \8 \ | \
The correct factors are 2 and 6.
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)
Combine like terms using distributive property: ac + bc = (a + b)c.
\The solution is "true".
The solution is .
