f%28x%29=x%5E2-x%2B1
f%280%29=0%5E2-0%2B1
f%280%29=1

f%28x%29=x%5E2-x%2B1=0
Use the quadratic formula,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-%28-1%29+%2B-+sqrt%28%28-1%29%5E2-4%2A1%2A1+%29%29%2F%282%2A1%29+
x+=+%281+%2B-+sqrt%281-4+%29%29%2F2+
x+=+%281+%2B-+sqrt%28-3+%29%29%2F2+
highlight%28x+=+%281+%2B-+sqrt%283%29i%29%2F2%29+ where i=sqrt%28-1%29
