Two friends wash cars to make extra money. The profit P(x) of one friend after x days can be represented by the function P(x) = −x2 + 9x + 10. The second friend's profit can be determined by the function Q(x) = 12x. Solve the system of equations. What solution is a viable answer to the question, "After how many days will the two students earn the same profit?" and which solution is a nonviable answer? Show your work and justify your answer.

Solving a systemof eqns by given initial conditions
x(t)=2x+8y
y(t)=x2y
Which has the I.C. X(0)=(6,2). So I take that it means this:
6=2x+8y
2=x2y
and then it is solved as any other system? We get eigenvector (1,12), but since the eigenvalues of the system are two, ±2i, we have to find the second generalized eigenvector.
(2-2i8-1-2-2i)(112)=(6-2i-2-i)
So the second vector would be (62i,2i). Using the general solutions for the system, we get
y(t)=e2it(1,12)+e2it(62i,2i)
Would this be correct, or did I misinterpret the initial conditions?

Solving 2nd order homogenous linear ODE with a squared coefficient
I am attempting to solve a differential equation of the form:
d2fdx2γ2f=0
I have set up and solved the characteristic equation as:
z2γ2z+0z=0z(zγ2)=0
which is satisfied when z=0 and when z=γ2
There are two distinct roots (r1 and r2) hence the general solution should be of the form
f(x)=Aer1x+Ber2x
In this case:
f(x)=Ae0×x+Beγ2x =A+Beγ2x
Apparently, this solution is incorrect as in the answers it is given as:
f(x)=Aeγx+Beγx
I would like to know where I went wrong to give me the incorrect solution
