The left and right focal points of hyperbola x2 / a2-y2 / B2 = 1 (a > 0, b > 0) are F1 and F2 respectively. The segment F1F2 is divided into two segments of 3:2 by the point (B / 2,0), which is the eccentricity of hyperbola

F1F2 is divided into 3:2 segments by point (B / 2,0)
b/2+c:c-b/2=3:2
c=5b/2
c^2=25b^2/4=25(c^2-a^2)/4
4=25(1-a^2/c^2)
4/25=1-1/e^2
e^2=25/21
e=5√21/21
