How do i re-write this equation in standard form?

You got to multiply, square that parenthesis and combine the like terms. kind of the opposite of simplifying.

y = -2(x+3)² - 4

y = -2(x+3)(x+3) - 4

y = -2(x² + 6x + 9) - 4

y = -2x² - 12x - 18 - 4

y = -2x² - 12x - 22

The answer is a 5/20 because if u add all of the marbles there are 20 and there are 5 red marbles so 5/20 is the answer mark as brainliest
