Suppose our expression is

    2๐‘ฅ − 3

 

Here we consider terms other than constant

For 4x3 โˆ’ 9xyz 4๐‘ฅ3 = 4 ร— ๐‘ฅ3 So 4 is the coefficient of ๐‘ฅ3 โˆ’9xyz = โ€“9 ร— xyz So, โˆ’9 is the coefficient of xyz For 25x + y 25x = 25 ร— ๐‘ฅ So, 25 is the coefficient of ๐‘ฅ y = 1 ร— y So, 1 is the coefficient of y For 15๐‘ฅy โˆ’ 25y + 18 15๐‘ฅy = 15 ร— ๐‘ฅ ร— y So 15 is the coefficient of xy โˆ’25y = โˆ’25 ร— y So, โˆ’25 is the Coefficient of y
