Question

the distance between the points (a,b)and (-a,-b)is​

Answer 1

Distance b/w the points ( a,b ) and ( -a, -b )

= √ ( a + a )² + ( b + b )²

= √ ( 2a )² + ( 2b )²

= √ 4a² + 4b²

$<marquee scrollamount = 700>✌️✌️✌️</marquee>$$<marquee scrollamount = 500>⭐⭐⭐</marquee>$

=>$\sqrt{(a-(-a))^2+(b-(-b))^2}$

=>$\sqrt{(2a)^2+(2b)^2}$

=>$\sqrt{4a^2+4b^2}$

=>$\sqrt{4(a^2+b^2)}$

=>$\large\orange{\fbox{\pink{2\sqrt{a^2+b^2}}}}$
