The trinomial expression is .

The trinomial compare to general trinomial expression: , So a = 10, b = 11, c = 6.

To find two numbers with a sum of 11 and a product of .

This trinomial list of the factors of 60, and look for the pair of factors is a sum of 11.

Factors of 60	Sum of factor
\ 5, 12 \ 6, 10 \ 4, 15 \	\ 7 \ 4 \ 11 \

The correct factors are 4 and 15.

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 negative.

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

The solution is "true".

The solution is .
