Final Answer:

The general form of the parabola with the equation (y-3)²=6(x-8) is:

y² = 6x + 6y - 57.

Step-by-step explanation:

To transform the equation (y-3)² = 6(x-8) into the general form of a parabola, expand the squared term:

(y-3)² = 6(x-8)

y² - 6y + 9 = 6x - 48

Rearrange terms to put it in the general form of a parabola:

y² - 6y = 6x - 48 - 9

y² - 6y = 6x - 57

Now, complete the square for the y terms by adding and subtracting the square of half the coefficient of y (which is (-6/2) = -3):

y² - 6y + (-3)² = 6x - 57 + (-3)²

y² - 6y + 9 = 6x - 57 + 9

y² - 6y + 9 = 6x - 48

Factor the left-hand side as a perfect square:

(y - 3)² = 6x - 48

To get the general form y² = ax + bx + c, expand the squared term:

(y - 3)² = 6x - 48

y² - 6y + 9 = 6x - 48

Rearrange terms to obtain the general form:

y² = 6x - 48 - 9 + 6y

y² = 6x - 57 + 6y

y² = 6x + 6y - 57

Finally, arrange the terms in descending order:

y² = 6x - 57 + 6y

y² = 6x + 6y - 57

Therefore, the general form of the parabola's equation is y² = 6x + 6y - 57.
