求助，怎么提出来0.0101122...那个解

h = 1.05457266*10^-34;
\[CapitalOmega]d = 200000*\[Pi];
ka = 400000*\[Pi];
kb = 400000*\[Pi];
kc = 2000*\[Pi];
\[CapitalDelta]a = 2000000*\[Pi];
\[CapitalDelta]b = 2000000*\[Pi];
wc = 2000000*\[Pi];
g = 800000*\[Pi];
\[Lambda]a = ka + I*\[CapitalDelta]a;
\[Lambda]b = kb + I*\[CapitalDelta]b;
\[Lambda]c = kc^2 + wc^2;
\[Lambda]ao = ka - I*\[CapitalDelta]a;
\[Lambda]bo = kb - I*\[CapitalDelta]b;
\[Delta] = x*wc;
t = (\[Lambda]a + \[Lambda]b)^2*(\[Lambda]ao + \[Lambda]bo);
to = (\[Lambda]ao + \[Lambda]bo)^2*(\[Lambda]a + \[Lambda]b);
Q = (4*g^4*
wc^2*(\[Lambda]a + \[Lambda]b)^3*(\[Lambda]ao + \[Lambda]bo)^3)/(\
\[Lambda]c^2*\[Lambda]b^3*\[Lambda]bo^3);
W = (2*I*wc*
g^2*(\[Lambda]a + \[Lambda]b)*(\[Lambda]ao + \[Lambda]bo)*((\
\[Lambda]ao + \[Lambda]bo)*\[Lambda]a*\[Lambda]b - (\[Lambda]a + \
\[Lambda]b)*\[Lambda]ao*\[Lambda]bo))/(\[Lambda]c*\[Lambda]b^2*\
\[Lambda]bo^2);
R = \[Lambda]a*\[Lambda]ao;
T = -\[CapitalOmega]d^2;
Solve[Q*u^3 + W*u^2 + R*u + T == 0, u, Reals]
最后这个解跑出来有两个数，怎么取0.0101122....那个，我试了在方程后加&&和类似的方法，以及solution[[]]的方法都不行，求助！谢谢啦
