How to factor Trinomials with two variables?
Sometimes a trinomial might consists in couple variables. We can factor the trinomial into a comparable way for if it has only one variable. Ourselves can use the trial and error method (reverse FOIL method), the grouping method or the AC way.

Example:
Factor the following trinomials:
a) e² − 6ef + 9f²
b) 2x² + 7xy − 15y²

Solution:
a) e² − 6ef + 9f² = (e − 3f)²
b) 2x² + 7xy − 15y² = (2x − 3y)(x + 5y)

Factoring trinomials with deuce variables
Step 1: Find the My, Sum and the double numbers that “work”
Product = (First number) × (Last number)
Sum = (Middle Number)
Find two numbers that when multiplied gives the Product and while add gives the Sum.
Step 2: Split the mid term.
Step 3: User in twos plus remove that GCF of each group.
Step 4: Write in factored entry.
