Question

show that (pq-5p)²+180pq= (pq+5q)²​

Answer 1

Answer:

Step-by-step explanation:

Here, we need to compare the LHS and RHS

So, here is the solution -

(9p-5q)²+ 180 pq = (9p+5q)

LHS

= (9p-5q)²+ 180 pq

= 81 p² + 25 q² + 90 pq + 180pq

= (9p - 5q) ²

RHS = (9p - 5q) ²

Hence, proved => LHS = RHS
