Question

Помогите решить уравнение:

Answer 1

$frac{x {}^{2} + 1 }{x} + frac{x}{x {}^{2} + 1 } = 2.9 \ frac{x {}^{4} + x {}^{2} + x {}^{2} + 1 }{x(x {}^{2} + 1) } = 2.9 \ frac{(x {}^{2} + 1) {}^{2} }{x(x {}^{2} + 1)} = 2.9 \ frac{x {}^{2} + 1}{x} = 2.9 \ x {}^{2} + 1 = 2.9x \ x {}^{2} - 2.9x + 1 = 0 \ d = 8.41 - 4 = 4.41 \ x(1) = 2.5 \ x(2) = 0.4$
