Question

factorise 16p^2-8pq-25r^2+q^2​

Answer 1

Answer:

16 p 2 − 8 p q − 25 r 2 + q 2

Step-by-step explanation:

16p2−8pq−25r2+q216p2−8pq−25r2+q2

=16p2−8pq+q2−25r2=16p2−8pq+q2−25r2

=(4p−q)2−25r2=(4p−q)2−25r2

=(4p−q+5r)(4p−q−5r)

Answer 2

Answer:

16 p 2 − 8 p q − 25 r 2 + q 2

Step-by-step explanation:

16p2−8pq−25r2+q216p2−8pq−25r2+q2  

=16p2−8pq+q2−25r2=16p2−8pq+q2−25r2  

=(4p−q)2−25r2=(4p−q)2−25r2  

=(4p−q+5r)(4p−q−5r
