Question

[(9p-5q)×(9p-5q)]+180pq=(9p-5q)

Answer 1

Answer:

LHS = RHS

Step-by-step explanation:

LHS:-

[(9p-5q)^2]+180pq

= (81p^2 - 90pq + 25q^2) + 180pq

= 81p^2 + 90pq + 25q^2

RHS:-

(9p +5q) ^2

= 81p^2 + 90pq + 25q^2

                                                    LHS=RHS

                                                             Hence Proved
