do you mean?
(a+b)/(a-b)
+ (a-2b)(a+2b)/[(a-b)(a+b)]
- (a-3b)/(a+b)
if so then
(a+b)^2/[(a-b)(a+b)]
+ (a-2b)(a+2b)/[(a-b)(a+b)]
- (a-3b)(a-b)/[(a-b)(a+b)]
[ a^2 + 2 a b + b^2 + a^2-4b^2 -a^2 -4 ab + 3b^2]/ [(a-b)(a+b)]
= [a^2 -2ab ]/[(a-b)(a+b)]
= a (a-2b)/(a^2-b^2)
check arithmetic !
a+b/a-b + a²-4b²/a²-b² - a-3b/a+b
How to solve this question and how to take the LCM of followings?.
