x=1+4/x
X-4/X=1
(X*X-4)/X=1
X^2-4=X
X^2-X-4=0
USING THE QUADRATIC EQUATION:x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+WE GET:
X=(1+-SQRT[-1^2-4*1*-4 ])/2*1
X=(1+-SQRT[1+16])/2
X=(1+-SQRT17)/2
X=(1+-4.1231)/2
X=(1+4.1231)/2
X=5.1231/2
X=2.562 ANSWER.
X=(1-4.1231)/2
X=-3.1231/2
X=-1.562 ANSWER.
