Question

If x^2+4x-1=0 and x is positive then find the value of -
i) x+1/x
ii) x^2+1/x^2
help me in this question....​

Answer 1

Step-by-step explanation:

${x}^{2} + 4x + - 1 = 0$

so,

$x = \frac{ - b + or - \sqrt{ {b }^{2} - 4ac } }{2a}$

here b= 4, a=1, c= -1, so

X= solve for x and substitute in i) and ii)
