Answer 1

495 1) (a+b)^2/(a-b)(a+b)=
(a+b)/(a-b)
2) (3(a^2-2ab+b^2))/(6(a^2-b^2)=(3(a-b)^2))/(6(a-b)(a+b)
=(a-b)/(2(a+b)=(a-b)/(2a+2b)
3) (x-1)^2/(x-1)(x+1)=(x-1)/(x+1)
4) (5(m+n)^2)/(15(m-n)(m+n))
=(m+n)/(3m-3n)
494) 1) (a-1)(a+1))/(-(a-1)=
-(a+1)=1-a
2) (x+1)^2)/(x-1)(x+1)=(x+1)/(x-1)
3) = -1/(n-m)
4) (a-1)(a+1))/(a-1)^2=
(a+1)/(a-1)
