Answer: x=3
(2/3)^x (3/2)^2x = 27/8
(3/2)^-x (3/2)^2x = 27/8
(3/2)^-x+2x = 27/8
(3/2)^x = 27/8
(3/2)^x = 3^3/2^3
(3/2)^x = (3/2)^3
x=3
11/36

Let us expand that
![\sf f(x)=x(x+5)](https://tex.z-dn.net/?f=%5Csf%20f%28x%29%3Dx%28x%2B5%29)
![\sf f(x)=x^2+5x](https://tex.z-dn.net/?f=%5Csf%20f%28x%29%3Dx%5E2%2B5x)
Since it has
![\sf x^2](https://tex.z-dn.net/?f=%5Csf%20x%5E2%20)
in it, it is now a linear function.
So the answer is
