Question 1121196
<br>
The excluded values are the values of the variable for which the expression can not be evaluated.<br>
For an algebraic fraction, the excluded values are those which make the denominator of the fraction equal to 0, because a fraction with 0 denominator can not be evaluated.<br>
You factored the original fraction into<br>
{{{((k+5)(k-6))/((k-5)(k-6))}}}<br>
and then simplified to<br>
{{{(k+5)/(k-5)}}}<br>
But the excluded values are any which make the denominator of the ORIGINAL, UNSIMPLIFIED fraction equal to 0.<br>
So the excluded values are both k=5 and k=6.
