Hlo friend.. Cutiepie Here .

Here is ur answer :

We have to do the factorisation of equation

4a²+b²+25c²-4ab-10bc+20ca

➡️ Using identity : ( a + b + c ) ² = a² + b² + c² + 2ab + 2bc + 2ca

✴️(2a)² + (b)² + (5c)² + 2× 2a × b + 2 × b × 5c + 2 × 5c × 2a

✴️(2a + b + 5c)²

✔️(2a + b + 5c) ( 2a + b + 5c)
