Pranjal Gupta 2 years, 5 months ago

Given : 9(2a−b)2−4(2a−b)−13 Let us consider 2a−b=c So we get, =9c2−4c−13 We can further write it as =9c2−13c+9c−13 By taking out the common terms =c(9c−13)+1(9c−13) =(c+1)(9c−13) Let us replace c by 2a−b so we get 9(2a−b)2−4(2a−b)−13 Then, =((2a−b)+1)(9(2a−b)−13) ∴9(2a−b)2−4(2a−b)−13=(2a−b+1)(18a−9b−13)
