Answer:

32(x-1)²/33 +12(y-1/2)²/11 = 1

Step-by-step explanation:

The equation of the ellipse is:

8x² + 9y² - 16x - 9y + 2 = 0

First, let's rewrite the expression as:

(8x² - 16x) + (9y² - 9y) + 2 = 0

(8x² - 16x) + (9y² - 9y) + 2 - 2 = 0 - 2

(8x² - 16x) + (9y² - 9y) = -2

Now, we need to complete the squares, so we will add 8 and 9/4 to both sides to get:

(8x² - 16x + 8) + (9y² - 9y + 9/4) = -2 + 8 + 9/4

8(x² - 2x + 1) + 9(y² - y + 1/4) = 33/4

8(x - 1)² + 9(y - 1/2)² = 33/4

Finally, multiply by 4 and divide by 33 to get:

4(8)(x-1)² + 4(9)(y - 1/2)² = 4(33/4)

32(x-1)² +36(y-1/2)² = 33

32(x-1)²/33 +36(y-1/2)²/33 = 33/33

32(x-1)²/33 +12(y-1/2)²/11 = 1

Therefore, the answer is:

32(x-1)²/33 +12(y-1/2)²/11 = 1
