Answer:

[tex]x - 2x - 15 \: divided \: by \: x - 3[/tex]

  1. according to the above x²-2x-15 divided by the number below x-3 first I cancel out the x
  2. [tex]x - 2x - 15 \: divided \: by \: - 3[/tex]
  3. the we solve the next x-5 divided by x²-9 then as usual rule out the x
  4. [tex] - 5 \: divided \: by \: x - 9[/tex]
  5. now we only have x-2x-15 divided by-3 divided by-5÷x-9 now our next step is to again single the equations out
  6. [tex]x - 2x - 15 \: divided \: by \: - 3 \: lets \: rue \\s \: rule \: out \: - 3 \: and \: 15 \: giving \: us \: x - 2x - 5[/tex]
  7. now the next -5 divided by x-9 here there's nothing to rule out therefore the sign "÷" is changed to "×" cancel out the -5 and therefore we have
  8. [tex]x - 2x = x - 9 \: as \: final \: answer[/tex]
