Example 11 Obtain the factors of ๐ง^2 โ 4z โ 12. ๐ง^2 โ 4z โ 12 By middle term splitting = ๐ง^2+"2z"โ6๐ง โ 12 = (๐ง^2+"2z" )โ(6๐ง + 12) Both have z as common factor Both have 6 as common factor = z (z + 2) โ 6 (z + 2) Taking (z + 2) common = (z + 2) (z โ 6) Splitting the middle term We need to find two numbers whose Sum = โ4 Product = โ12 So, we write โ4z = 2z โ 6z
