Question

1/x+1/15-x=3/10 factorise
​

Answer 1

Step-by-step explanation:

$\frac{1}{x} + \frac{1}{15} - x = \frac{3}{10} \\ \frac{15 + x - 15 {x}^{2} }{15x} = \frac{3}{10} \\ 2(15 + x - 15 {x}^{2} ) = 3 \times 3x \\ 30 + 2x - 30 {x}^{2} = 9 {x}^{2} \\ 39 {x}^{2} - 2x - 30 = 0 \\ applying \: shridhar \: acharyas \: formula \: we \: have \\ x = \frac{ - b + \sqrt{ {b }^{2} - 4ac } }{2a} \: and \: x = \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a}$
