Question

Factorise: 9(2x−y)2−4(2x−y)−13

Let (2x−y)=p, then the equation 9(2x−y)2−4(2x−y)−13 becomes 9p2−4p−13

Consider the expression 9p2−4p−13 we can factorise it as follows:

9p2−4p−13=9p2+9p−13p−13=9p(p+1)−13(p+1)=(9p−13)(p+1)

Now, substitute the value of p as p=(2x−y):

(9p−13)(p+1)=(9(2x−y)−13)(2x−y+1)=(18x−9y−13)(2x−y+1)

Hence, 9(2x−y)2−4(2x−y)−13=(18x−9y−
