Example 10 Find the factors of ๐ฆ^2 โ 7y + 12. ๐ฆ^2 โ 7y + 12 By middle term splitting = ๐ฆ^2 โ 3๐ฆ โ 4๐ฆ+12 = (๐ฆ^2 โ 3๐ฆ) โ(4๐ฆโ12) Both have y as common factor Both have 4 as common factor = y (y โ 3) โ 4 (y โ 3) Taking (y โ 3) common = (y โ 3) (y โ 4) Splitting the middle term We need to find two numbers whose Sum = โ7 Product = 12 So, we write โ7y = โ3y โ 4y
