Answer 1

Answer:

+x1=3−22+3−221

+x1=3−22+3−221x1=3−221×3+223+22

+x1=3−22+3−221x1=3−221×3+223+22 =13+22

+x1=3−22+3−221x1=3−221×3+223+22 =13+22x+x1

+x1=3−22+3−221x1=3−221×3+223+22 =13+22x+x1=3−22+3+22

+x1=3−22+3−221x1=3−221×3+223+22 =13+22x+x1=3−22+3+22 

+x1=3−22+3−221x1=3−221×3+223+22 =13+22x+x1=3−22+3+22 =6

+x1=3−22+3−221x1=3−221×3+223+22 =13+22x+x1=3−22+3+22 =6Squaring on both sides, 

+x1=3−22+3−221x1=3−221×3+223+22 =13+22x+x1=3−22+3+22 =6Squaring on both sides, (x+x1)2=36
