Question 460083
find a quadratic equation with the given solution:
a)3 + or - sqrt of 5
{{{(x - 3 + sqrt(5))*(x - 3 - sqrt(5)) = 0}}}
{{{x^2 - 6x + 9 - 5 = 0}}}
{{{x^2 - 6x + 4 = 0}}}
------------
b)(1 + or - sqrt of 5)/2
{{{(x -1/2 - sqrt(5)/2)*(x -1/2 + sqrt(5)/2) = 0}}}
{{{x^2 - x + 1/4 - 5/4 = 0}}}
{{{x^2 - x - 1 = 0}}}
