This will help you start:

y=+-3x%5E2+%2B+30x+%2B+7
y=-3%2A%28x%5E2-10x%29%2B7
The square term to Complete the Square is %2810%2F2%29%5E2=25 or 5%5E2.
y=-3%2A%28x%5E2-10x%2B%28something%29%29%2B7-%28somethingelse%29.
Something is added inside the parentheses and something related to it is subtracted outside the parentheses.
