Question

$frac{1}{a} - frac{ a^{2}-25 }{5a} + frac{a}{5}$

Answer 1

$frac{1}{a}- frac{a^2-25}{5a}+ frac{a}{5}= frac{5-(a^2-25)+a^2}{5a}= frac{5-a^2+25+a^2}{5a}= frac{30}{5a}= frac{6}{a}$

Answer 2

$frac{1}{a} - frac{ a^{2}-25 }{5a} + frac{a}{5} = frac{5}{5a} - frac{ a^{2}-25 }{5a} + frac{a^2}{5a} = frac{5-a^2+25+a^2}{5a} = frac{30}{5a} =frac{6}{a}$
