Question

10x-1/x=3 solve in factorisation method.
Please solve this urgently.​

Answer 1

Answer:

Given:-

${10x } - \frac{1}{x} = 3$

Solution:-

${10 {x}^{2} }^{} - 1 = 3x$

$10 {x}^{2} - 3x - 1 = 0$

Product= -10

Sum= -3

Numbers= -5,2

$10 {x}^{2} - 5x + 2x - 1 = 0$

=5x(2x-1)+1(2x-1)=0

=(5x+1)(2x-1)=0

=(5x+1=0) or 2x-1=0

$x = \frac{1}{2} \: \: and \: \: \frac{ - 1}{5}$
