[ (x^2-2x+24)/(x^2+2x+1) ]^3 *[ (x+1)/(x-6) ]^4 *[ 1/(x+4) ]^3
[ (x^2-2x+24)/(x^2+2x+1) ]^3 *[ (x+1)/(x-6) ]^4 *[ 1/(x+4) ]^3

[ (x^2-2x+24)/(x^2+2x+1) ]^3 *[ (x+1)/(x-6) ]^4 *[ 1/(x+4) ]^3
应该是:
[ (x^2-2x-24)/(x^2+2x+1) ]^3 *[ (x+1)/(x-6) ]^4 *[ 1/(x+4) ]^3
=(x-6)^3(x+4)^3/(x+1)^6*(x+1)^4/(x-6)^4*1/(x+4)^3
=1/(x+1)^2(x-6)
