Math Help - Help MAth7 solutions

1. Help MAth7 solutions

Hi everybody.. I am new on the forum and I will say that the forum is fantastic. I can search and find many things. I have a problem with mathematic 7. It can not give me the solutions in next form: x1(s), x2(s)

How can I get that????

Solve[{x^2 - (N1 + N2 - n1*F1 - n2*F2)*x + (N1 - n1*F1)*(N2 - n2*F2) -
H1*H2 ==
0, (N1 - H1)*R*A1 == (E0*I1*k^4), (N2 - H2)*R*A2 == (E0*I2*k^4),
n1 == k^2/(R*A1), n2 == k^2/(R*A2), H1 == K0/(R*A1),
H2 == K0/(R*A2), E0 == 10^10, A1 == (s1*l)^2, A2 == (s2*l)^2,
K0 == 2*10^5, I1 == ((s1*l)^4)/3, I2 == ((s2*l)^4)/3, R == 2*10^3,
F1 == 10, F2 == 10, k == n*2/l, l == 10, n == 1, s1 == s, s2 == s},x]

It is very difficult to understand what you are asking. Please wrte those as separate equations. Also what is the relationship between " $x_1$" and " $x_2$" and "x"?

3. x1 and x2 are solutions of the equation: x^2 - (N1 + N2 - n1*F1 - n2*F2)*x + (N1 - n1*F1)*(N2 - n2*F2) - H1*H2 == 0. But I want to get this solutions in function of s???
