Question 628150
Please re-post your question. You have two {{{m^2}}} terms. If this is correct, then they cancel each other out and your expression is
{{{-m^4+m^3+5}}}. Post this simplified expression.<br>
But I suspect that the first term has an exponent higher than 4 since polynomials are usually written in order from highest exponent to lowest.<br>
P.S. According to your note, you posted the problem correctly. We should start then by simplifying {{{m^2-m^4+m^3-m^2+5}}} to {{{-m^4+m^3+5}}} which we will now divide by m-4 using synthetic division:
<pre>
4 }   -1    1    0    0     5   <== two zeros for the missing x^2 and x terms
===        -4  -12  -48  -192
      =======================
      -1  -3   -12  -48  -187
which matches what you got with long division.
