x^2 - 17 x + 72 = 0
a=1 and b=-17 and c=72
x+=+%28-b+%2B-+sqrt%28+b%5E2+-+4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%2817+%2B-+sqrt%28+%28-17%29%5E2+-+4%2A72+%29%29%2F%282%29+
x+=+%2817+%2B-+sqrt%28+289+-+288+%29%29%2F%282%29+
x+=+%2817+%2B-+1%29%2F%282%29+
x+=+%2817+%2B+1%29%2F%282%29+ and x+=+%2817+-+1%29%2F%282%29+
x+=+%2818%29%2F%282%29+ and x+=+%2816%29%2F%282%29+
