大家帮忙解一下这个方程吧,小弟先感谢了
4022+(12+x-(373.6+1.18*x)*(2+x)/(771+3.54*x))*(257+129.68*x+0.59*x*x)=(41.7*x+16.9*x*...
4022+(12+x-(373.6+1.18*x)*(2+x)/(771+3.54*x))*(257+129.68*x+0.59*x*x)=(41.7*x+16.9*x*x)*(12+x-x*(125.1+33.8*x)/(250.2+101.4*x))

在MATLAB中运行
solve('4022+(12+x-(373.6+1.18*x)*(2+x)/(771+3.54*x))*(257+129.68*x+0.59*x*x)=(41.7*x+16.9*x*x)*(12+x-x*(125.1+33.8*x)/(250.2+101.4*x))')
答案是:
ans =
