`a^(2)+b^2`=....

Simplify: (a^(2)-(b-c)^(2))/((a+c)^(2)-b^(2))+(b^(2)-(a-c)^(2))/((a+b)^(2)-c^(2))+(c^(2)-(a-b)^(2))/((b+c)^(2)-a^(2))

Evaluate ((a)/(2b)+(2b)/(a))^(2)-((a)/(2b)-(2b)/(a))^(2)-4 .

(a + 2b)^(2) - (a - 2b)^(2) = 8ab

(a+2b)^2-(a-2b)^2 is equal to: (a+2b)^2-(a-2b)^2 का मान है :

Simplify: (a+b)^^2(a-b)^^2(a^(^^)2-ab+b^(^^)2)(a^(^^)2+ab+b^(^^)2)(a^(^^)4+a^(^^)2b^(^^)2+b^(^^)4)(a^(^^)6+b^(^^)6)^(^^)2'
