a-5 a+5 5
(_____ _____ - _________) ÷﹙_______ _1)
a²-10a+25 a²-5a a
(_____ _____ - _________) ÷﹙_______ _1)
a²-10a+25 a²-5a a
a-5 a+5 5 (_____ _____ - _________) ÷﹙_______ _1) a²-10a+25 a²-5a a
=1/(a-5)+(a+5)/[a(5-a)]/(5-a)/a
=1/(a-5)+(a+5)*1/[a(5-a)]*a/(5-a)
=1/(a-5)+(a+5)/(5-a)^2
=[(a+5)-(5-a)]/(5-a)^2
=2a/(5-a)^2 .
=1/(a-5)+(a+5)/[a(5-a)]/(5-a)/a
=1/(a-5)+(a+5)*1/[a(5-a)]*a/(5-a)
=1/(a-5)+(a+5)/(5-a)^2
=[(a+5)-(5-a)]/(5-a)^2
=2a/(5-a)^2 .
