Question

if x+1/x =6 then find x-1/x

Answer 1

Answer:

x+1/x =6  

x+1=6x

1/5=x

(1/5)-1/(1/5)

-4

Answer 2

Answer:

${(x - \frac{1}{x} )}^{2} = {x}^{2} + \frac{1}{x {}^{2} } + 2 \: \times x \times \frac{1}{x} \\ = {x}^{2} + {\frac{1}{x}}^{2} + 2 \\ = 6 + 2 \\ = 8$

therefore,

$(x - \frac{1}{x}) = \sqrt{8}$
