Question 1097589
Please help with the following:
Solve the equation and show the check of the potential answer(s).  If any answers are excluded values, state it.

1= ( 1/(n^2-n)) + (( n^2+n-20)/ (n^2-n))
Thanks! 
<pre>{{{matrix(1,3, 1, "=", 1/(n^2 - n) + (n^2 + n - 20)/(n^2 - n)))}}}
Setting denominator: n<sup>2</sup> - n equal to 0, we see and NEED to be AWARE that: {{{matrix(2,1, n <> 0, n <> 1)}}} 
{{{matrix(1,3, 1(n^2 - n), "=", 1 + n^2 + n - 20)}}} ----- Multiplying by LCD, n<sup>2</sup> - n 
{{{matrix(1,3, n^2 - n, "=", 1 + n^2 + n - 20)}}}
{{{matrix(1,3, n^2 - n^2 - n - n, "=", - 19)}}} 
- 2n = - 19
{{{highlight_green(matrix(1,5, n, "=", (- 19)/(- 2), "=", 9.5))}}}
