Answer:
Multiply both sides by x (check that x is not equal to 0 at the end as it would make the 1/x undefined)x^2 + 1 = 4xsubtract 4x from both sides of the equation.x^2 -4x + 1 = 0Use the quadratic formulax = (-(-4) +/- radical( (-4)^2 - 4*1*1) )/(2*1)x = ( 4 +/- radical(12) )/2x = ( 4 +/- 2*radical(3) )/2x = 2 +/- radical(3)
