Question

factorise = pqsquare+q(p-1)-1​​

Answer 1

Answer:

firstly lets simplify pq

2

+q(p−1)−1=pq

2

+pq−q−1

Now take the common factor as pq

we get

pq

2

+pq−q−1 =pq(q+1)−1(q+1)=(q+1)(pq−1)

Answer 2

Answer: ( pq - 1 ) ( q + 1 )

Step-by-step explanation:

Factorise : pq² + q ( p - 1 ) - 1

=> pq² + pq - q - 1

=> pq ( q + 1 ) - 1 ( q + 1 )

=> ( pq - 1 ) ( q + 1 )
