y+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29

y+=+%28-%28-12%29%2B-sqrt%28%28-12%29%5E2-4%285%29%2835%29%29%29%2F%282%285%29%29 Plug in a+=+5, b+=+-12, c+=+35

y+=+%2812%2B-sqrt%28144-%28700%29%29%29%2F%2810%29

y+=+%2812%2B-sqrt%28-556%29%29%2F10

y+=+%2812%2Bsqrt%28-556%29%29%2F10 or y+=+%2812-sqrt%28-556%29%29%2F10

y+=+%2812%2B2i%2Asqrt%28139%29%29%2F10 or y+=+%2812-2i%2Asqrt%28139%29%29%2F10

y+=+%286%2Bi%2Asqrt%28139%29%29%2F5 or y+=+%286-i%2Asqrt%28139%29%29%2F5
