Simplify the following
[2x / (3x (2nd power)  5x  2] + [(x1) / (x (2nd power) x  20)]

Algebra 
Reiny
let's write it this way
2x/(3x^2  5x  2) + (x1)/(x^2 x  20)
= 2x/[(3x+1)(x2)] + (x1)/[(x5)(x+4)]
Your LCD is (3x+1)(x2)(x5)(x+4)
Unusual, as I had expected one of the factors to be the same in the denominators.
anyway...
[2x(x5)(x+4) + (x1)3x+1)(x2)]/[(3x+1)(x2)(x5)(x+4)]
expand the top and collect like terms.
Good luck, since the result will certainly not be more simplified than the original.
