If A= `[(1,-1),(2,-1)]` and B = `[(a,1),(b,-1)] and(A+B)^(2)=A^(2)+B^(2)`, then the values of a and b are

If A=((1,-1),(2,-1)), B= ((a,1),(b,-1)) and (A+B)^(2)=A^(2)+B^(2) then the values of a and b are ................... .

If A=[(1,-1),(2,1)], B=[(a,1),(b,-1)] and (A+B)^(2)=A^(2)+B^(2)+2AB , then

If A= [(3,-1,0),(2,1,5)] ,B= [(2,2,1),(3,0,-2)] .Find A+B,2A-B

If A'=[(-2,3),(1,2)] and B=[(-1,0),(1,2)] then find (A+2B)'

If A=((1,2,1),(2,-1,1)) and B=((2,-1),(-1,4),(0,2)) show that (AB)^(T)=B^(T)A^(T)

If A=(2x+1)/(2x-1), B=(2x-1)/(2x+1) find (1)/(A-B)-(2B)/(A^(2)-B^(2))
