(2a)2 +(2b)2 +(2c)2

4a square + 4b square + 4c square

Answer 2

hey buddy,

here is your ans..

Answer:

=(b-c)²

Step-by-step explanation:

$x = a - b + c \\ y = b - c + a \\ \\ then \\ {( x - y)}^{2} \\ = (a - b + c - b + c - a) {}^{2} \\ =( - 2b + 2c) {}^{2} \\ = ( - 2b) {}^{2} + (2c) {}^{2} + 2( - 2b)(2c) \\ = 4b {}^{2} + 4c {}^{2} - 8bc \\ divide \: by \: 4 \\ = b {}^{2} + c {}^{2} - 2bc \\ = (b - c) {}^{2}$

I hope it helps you

thank you

have a great day ahead..✌✌
