Dividing (a+b)2+(a−b)2 by (a2+b2) gives___.
(a+b)2+(a−b)2
=(a2+b2+2ab)+(a2+b2−2ab)
=2(a2+b2)
Thus, ((a+b)2+(a−b)2)(a2+b2)=2
Dividing (a+b)2+(a−b)2 by (a2+b2) gives ___
Dividing (a+b)2+(a−b)2 by a2+b2 gives:
Which of the following is correct? a) (a−b)2=a2+2ab−b2 b) (a−b)2=a2−2ab+b2 c) (a−b)2=a2−b2 d) (a+b)2=a2+2ab−b2
