" If "A={x in C:x^(2)=1}" and "B={x in C:x^(4)=1}," then write "A-B" and "B-A

If quad {x in C:x^(2)=1} and B={x in C:x^(4)=1} ,then write A-B and B-A .

If A={x in C : x^2=1}\ a n d\ B={x in C : x^4=1} , then write A-B\ a n d\ B-Adot

If A={x in C:x^2=1} and B={x in C:x^4=1} ,then AcupB is :

If A = x^(3), B = 4x^(2) + x -1, C = x +1 , then find (A -B) (A-C)

I : If (x^(2)+x+1)/(x^(2)+2x+1)=A+B/(x+1)+C/(x+1)^(2) " then "A+B+C=0 . II : If (x^(2)+2x+3)/x^(3)=A/x+B/x(2)+C/x^(3) " then "A+B-C=0 .

If a,b are the zeroes of f(x)=x^(2)+3x+1 and c, d are the zero of g(x)=x^(2)+4x+1 then the value E=((a-c)(b-c)(a+a)(b+d))/(2) is

If the A.M. of (1)/(b-a) and (1)/(b-c) is (1)/(2(b-x)) , then show that (x-b)^(2) = (x-c)(x-a) .

If (x^(2)+x+1)/(x^(2)+2x+1)=A+B/(x+1)+C/(X+1)^(2) , then A+B+C=
