Question 177650
simplify the rational expression:
{{{(x^2 +3x - 10)/(x^2 + x -20)}}}
<pre><font size = 4 color = "indigo"><b>
Factor numerator and denominator:

{{{((x+5)(x-2))/((x+5)(x-4))}}}

Cancel the {{{(x+5)}}}'s

{{{(cross((x+5))(x-2))/(cross((x+5))(x-4))}}}

All that's left is

{{{(x-2)/(x-4)}}}
