I assume you mean (x^2 - 15*x - 36) / (5x - 60). Notice that you can factor a 5 out of the denumerator (the bottom), to get 5 * (x - 12). You could then try factoring the numerator (the top part), and you will probably be able to cancel out a term on top and bottom.
Answer:
My answer to the question is
x= -2.
Answer:
Let the 3 digits are xyz.
For x we have 6 options, for y - 5, for z - 4 since all digits are different.
<u>Number of options:</u>
Even numbers will have z = 2, 4 or 6, then
x - 5 options, y - 4 options
<u>Number of options:</u>
