Simplifying (Math)
posted by Reina on .
[a + (8a^2)] / [1 + (2a^1)]
and
[(x^1) + (y^1)] /[(x^1)  (y^1)]
No idea where to begin simplifying. Suggestions and help are greatly appreciated.

[ a + 8/a^2 ]/ [1 + 2/a ]
multiply top and bottom by a^2
[a^3 + 8a ] / [a^2 + 2 a ]
[a^2 + 8] /[ a^2 + 2 ]
[ 1/x + 1/y ]/[1/x  1/y]
multiply top and bottom by x y
[y+x]/[yx]
