x^2-6x+11=0
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x=(6+-sqrt[-6^2-4*1*11])/2*1
x=(6+-sqrt[36-44])/2
x=(6+-sqrt-8)/2
x=(6+-2.828i)/2
x=(6/2)+-2.828i/2
x=3+-1.414i ans.

Using x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
where a = 1 , b = -6 and c = 11
x+=+%286+%2B-+sqrt%28+%28-6%29%5E2-4%2A%281%29%2A%2811%29+%29%29%2F%282%2A1%29+

x+=+%286+%2B-+sqrt%28+-8%29%29%2F%282%29+
x+=+%286+%2B-+2%2A2i%29%2F%282%29+
x+=+%286+%2B+4i%29%2F2+ or x+=+%286+-+4i%29%2F2+
x+=+%283+%2B+2i%29+ or x+=+%283+-+2i%29+
where i is the imaginary number
