The trinomial expression is
.
The trinomial compare to general trinomial expression:
, So a = 2, b = 7, c = 5.
To find two numbers with a sum of 7 and a product of
.
This trinomial list of the factors of 10, and look for the pair of factors is a sum of 7.
\| Factors of 10 | \Sum of factor | \
| \
10, 1 \ \ \2, 5 \ | \
\
11 \ \ \7 \ | \
The correct factors are 2 and 5.
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
.
