Step-by-step explanation:

( 2a + 2b - 3c )² + 2( a - 3b + 7c )² - ( -5a - 8b + 2c )²

( 2a + 2b - 3c)² - ( -5a - 8b + 2c )² + 2( a - 3b + 7c )²
[ 2a + 2b - 3c + ( -5a - 8b + 2c )] [ 2a + 2b - 3c - ( -5a - 8b + 2c)] + 2( a - 3b + 7c)²
[ -3a - 6b - c ] [ 7a + 10b - 5c ] + 2( a - 3b + 7c )²

it can be correct or incorrect

but mark me as brainlist
