The value of `(a+b)^2-(a-b)^2` is

Find the value of ( a + b )^2 /(( a^2 - b^2 )) is

Find the value of ( a + b )^2 - 2 ( a - b )^2 + ( a - b ) ( a + b )

If the value of (a+b-2)^2+ (b+c-5)^2+ (c+a-5)^2=0 , then the value of sqrt((b+c)^a+(c+a)^b-1) is : यदि (a+b-2)^2+ (b+c-5)^2+ (c+a-5)^2=0 है, तो sqrt((b+c)^a+(c+a)^b-1) का मान क्या होगा ?

If y=f(x)=ax+b is a tangent to circle x^2+y^2+2x+2y-2=0 then the value of (a+b)^2 +2(a-b)(a+b+1) is equal to

If (2x-1) is exactly divides 6x^(2)+ax-4 and bx^(2)-11x+3 ,then the value of b^(2)-a^(2)+a-b is
