Question

Show that ( 9p - 5q )^2 + 180pq = ( 9p +5q)^2

Answer 1

Answer:

hope this helps u

Step-by-step explanation:

So, here is the solution -

(9p-5q)²+ 180 pq = (9p+5q)

LHS

= (9p-5q)²+ 180 pq

= 81 p² + 25 q² -90 pq + 180 pq

= (9p + 5q) ²

l.h.s = r.h.s

Answer 2

Answer:

Step-by-step explanation:

(9p-5q)²+ 180 pq = (9p+5q)

LHS

= (9p-5q)²+ 180 pq

= 81 p² + 25 q² -90 pq + 180 pq

= (9p + 5q) ²

l.h.s = r.h.s
