Let a=6
Let b=2
Let c=1
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-2+%2B-+sqrt%28+%282%29%5E2-4%2A6%2A1+%29%29%2F%282%2A6%29+
x+=+%28-2+%2B-+sqrt%28+4-24+%29%29%2F%2812%29+
x+=+%28-2+%2B-+sqrt%28+-20+%29%29%2F%2812%29+
x+=+%28-2+%2B-+2i%2Asqrt%285%29%2F%2812%29%29+
x+=+%28%28-1+%2B-+i%2Asqrt%285%29%29%2F%286%29%29+
