Example 10 Find the factors of š‘¦^2 ā€“ 7y + 12. š‘¦^2 ā€“ 7y + 12 By middle term splitting = š‘¦^2 āˆ’ 3š‘¦ āˆ’ 4š‘¦+12 = (š‘¦^2 āˆ’ 3š‘¦) āˆ’(4š‘¦āˆ’12) Both have y as common factor Both have 4 as common factor = y (y āˆ’ 3) āˆ’ 4 (y āˆ’ 3) Taking (y āˆ’ 3) common = (y āˆ’ 3) (y āˆ’ 4) Splitting the middle term We need to find two numbers whose Sum = āˆ’7 Product = 12 So, we write āˆ’7y = āˆ’3y āˆ’ 4y
