Quadratic formula is
x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a
from ax%5E2%2Bbx%2Bc=0
...
Starting with x%5E2%2B5x%2B6+=+0
x+=+%28-5+%2B-+sqrt%285%5E2-4%281%29%286%29%29%29%2F%282%281%29%29
x+=+%28-5+%2B-+sqrt%2825-24%29%29%2F2
x+=+%28-5+%2B-+sqrt%281%29%29%2F2
x = %28-5%2B1%29%2F2+=+-4%2F2+=+highlight_green%28-2%29
AND
x = %28-5-1%29%2F2+=+-6%2F2+=+highlight_green%28-3%29
...
Starting with 8x%5E2-10x-12+=+0
x+=+%28-%28-10%29%2B-sqrt%28%28-10%29%5E2-4%288%29%28-12%29%29%29%2F%282%288%29%29
x+=+%2810%2B-sqrt%28100%2B384%29%29%2F%2816%29
x+=+%2810%2B-sqrt%28484%29%29%2F16
x+=+%2810%2B-22%29%2F16
x = %2810-22%29%2F16+=+-12%2F16+=+highlight_green%28-3%2F4%29
AND
x = %2810%2B22%29%2F16+=+32%2F16+=+highlight_green%282%29
