2（x^2+1/x^2）+3(x+1/x)-16=0【如果你没算错的话】所以：2*(x^2+1/x^2+2)+3(x+1/x)-20=02*(x+1/x)^2+3*(x+1/x)-20=0令t=x+1/x所以：2t^2+3t-20=0(2t-5)(t+4)=0解得：t=5/2 或者 t=-4所以：x+1/x=5/2 或者x+1/x=-4解...
Interestingly, TCF/LEF binding sites were found in a cis-regulatory module of the SHH-inducible ventral marker Nkx2.2, and it appears that in the mouse embryo the dorsal limit of Nkx2.2 expression is established through repression by TCF/LEFs, rather than threshold-dependent induction by SHH [...
