An equation that lets you read the vertex:

y=3%28x%5E2%2B3x-10%29
3%28x%5E2%2B3x%2B%283%2F2%29%5E2-%283%2F2%29%5E2-10%29
3%28%28x%2B3%2F2%29%5E2-9%2F4-10%29
3%28%28x%2B3%2F2%29%5E2-9%2F4-40%2F4%29
3%28%28x%2B3%2F2%29%5E2-49%2F4%29
highlight%28y=3%28x%2B3%2F2%29%5E2-147%2F4%29


An equation in descending degree on variable:
3%28x%5E2%2B3x-10%29
highlight%28y=3x%5E2%2B9x-30%29
