Question

(i) (9p - 5q)² +180pq=(9p +59)²​

Answer 1

Step-by-step explanation:

Heya!!

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 + 180 pq

= (9p - 5q) ² 2

RHS = (9p - 5q) ²

Hence, proved => LHS = RHS

Hope it helps!!

Answer 2

Answer:(9p−5q)  

2

+180pq=(9p+5q)  

2

 

LHS=(9p)  

2

−2(9p)(5q)+(5q)  

2

+180pq

      =81p  

2

−90pq+25q  

2

+180pq

      =81p  

2

+90pq+25q  

2

 

RHS=(9p+5q)  

2

 

      =(9p)  

2

+2(9p)(5q)+(5q)  

2

 

      =81p  

2

+90pq+25q  

2

 

LHS=RHS
