Question

Split the middle term
X+1/X=2.1/20. (2.1/20 IS MIXED FRACTION)

Answer 1

Step-by-step explanation:

$\sf \leadsto x + \frac{1}{x} = \frac{2.1}{20} \\ \sf \leadsto \frac{ {x}^{2} + 1 }{x} = \frac{21}{ \dfrac{10}{20} } \\ \sf \leadsto \frac{x {}^{2} + 1}{x} = \frac{21}{200} \\ \sf \leadsto 200 {x}^{2} + 200 = 21x \\ \sf \leadsto 200 {x}^{2} - 21x + 200 = 0$
