If `A=[[a,b],[-1,2]],B=[[1,1],[2,4]]` and `(A+B)(A-B)=A^(2)-B^(2)`, then the value of `a+b` equals

If A=[[1,-1],[2,-1]],B=[[a,1],[b,-1]] and (A+B)^(2)=A^(2)+B^(2) , the value of a+b is

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

If A=[[1,-12,-1]] and B=[[a,1b,-1]] and (A+B)^(2),=A^(2)+B^(2), then find the value of a and b.

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

If A= [[3,4],[-4,3]] and B= [[2,1],[-1,2]] ,show that (A+B)(A-B)=A^2-B^2

If A=[{:(1,2),(-1,-2):}], B=[{:(2,a),(-1,b):}] and (A+B)^(2) =A^(2) + B^(2) , then find the value of a and b.

If A=[{:(1,-1),(2,-1):}],B=[{:(a,-1),(b,-1):}]" and "(A+B)^(2)=(A^(2)+B^(2)) then find the values of a and b.

Let a=[(1,-1),(2, -1)] and B=[(a,1),(b,-1)] are two matrices. If (A+B)^(2)=A^(2)+B^(2) , then the value of 3a+4b is equal to
