Answer:

Step-by-step explanation:

4a  2 +b  2+c  2

−4ab+2bc−4ca

=(2a)  

2

+(−b)  

2

−(c)  

2

−2(2a)(−b)+2(−b)(−c)+2(2a)(−b)

We know that x  

2

+y  

2

+z  

2

+2xy+2yz+2xz=(x+y+z)  

2

 

Here, x=2a, y=−b and z=−c

4a  

2

+b  

2

+c  

2

−4ab+2bc−4ca

=(2a)  

2

+(−b)  

2

−(c)  

2

−2(2a)(−b)+2(−b)(−c)+2(2a)(−b)

=(2a−b−c)  

2

=(2a−b−c)(2a−b−c)
