2^5*x-3 = (4^1)/x // - (4^1)/x
2^5*x-((4^1)/x)-3 = 0
2^5*x-4*x^-1-3 = 0
32*x^1-4*x^-1-3*x^0 = 0
(32*x^2-3*x^1-4*x^0)/(x^1) = 0 // * x^2
x^1*(32*x^2-3*x^1-4*x^0) = 0

32*x^2-3*x-4 = 0
32*x^2-3*x-4 = 0
DELTA = (-3)^2-(-4*4*32)
DELTA = 521
DELTA > 0
x = (521^(1/2)+3)/(2*32) or x = (3-521^(1/2))/(2*32)
x = (521^(1/2)+3)/64 or x = (3-521^(1/2))/64
