Question

196/x - 196/x+21 =11 solution of x is

Answer 1

Wrong question well...
+196/x-196/x
Both gets cancelled

Answer 2

here.......

$\frac{196}{x} - \frac{196}{x + 21} = 11$

$196( \frac{1}{x} - \frac{1}{x + 21} ) = 11$


$\frac{1}{x} - \frac{1}{x + 21} = \frac{11}{196}$


$\frac{x + 21 - x}{x(x + 21) } = \frac{11}{196}$


$\frac{21}{ {x}^{2} + 21x } = \frac{11}{196}$


$11( {x}^{2} + 21x) = 21 \times 196$

$11 {x}^{2} + 231x = 4116$
$11 {x}^{2} + 231x - 4116 = 0$
solve this quadratic equation by formula method and get your answer.
