Question

Please help!!!!! It's urgent

;Both answers must be filled out the second set of the answers is

(b+a)(b-a)

(b+a)^2(b-a)

(b+a)^2(b^2-a^2)

Answer 1

2b 2a
----------------- + -----------------
(b+a)^2 (b^2 - a^2)

2b 2a
= ----------------- + -------------------
(b+a)(b+a) (b+a)(b-a)

2b(b - a) + 2a(b + a)
= ------------------------------------
(b+a)(b+a)(b-a)


2b^2 - 2ab + 2ab + 2a^2
= ---------------------------------------
(b+a)(b+a)(b-a)

2b^2 + 2a^2
= ------------------------
(b+a)(b+a)(b-a)

2(b^2 + a^2)
= ------------------------
(b+a)^2 (b-a)

Answer:

Numerator: 2(b^2 + a^2)
Denominator: (b+a)^2 (b-a)
