Final answer:
To find the standard form of the parabola 3x² + 24x - 2y + 52 = 0, divide by -2, complete the square, and rearrange to get y = -1.5(x + 4)^2 - 2. The vertex is (-4, -2) and the parabola opens downward.
Step-by-step explanation:
To convert the given general form of a parabola 3x² + 24x - 2y + 52 = 0 into the standard form, start by isolating the y-term on one side:
First, divide the entire equation by -2 to simplify.
y = -1.5x² - 12x - 26
Next, complete the square for the x-terms:
- Add (12/2)^2 = 36 to both sides to complete the square.
- Rewrite the equation incorporating the completed square and adjust the constant term accordingly.
y = -1.5(x + 4)^2 - 2
This is the standard form of the parabola, where the vertex can easily be determined as (-4, -2) and the parabola opens downward due to the negative coefficient of the x² term.
