Question

Factorise by using suitable identities:
Psquare + qsquare + 9rsquare + 2pq + 6qr + 6pr

Answer 1

Hey dear friend

Given
=>P²+Q²+9R²+2PQ+6QR+6PR

By Id.=>(a+b+c)²=a²+b²+c²+2ab+2bc+2ca
Compare with it
we get,
a=P
b=Q
c=3R

So, the factorisation of eq. is

(P+Q+3R)². ans.

perfectly fine pure correct answer
