Answer:
320 i think
Step-by-step explanation:
Answer:
x² = 8 - (y - 8)² - 2x
x² = 16y - y² - 2x - 56
Step-by-step explanation:
∵ (x + 1)² + (y - 8)² = 9
∵ x² + 2x + 1 = 9 - (y - 8)²
∴ x² = 9 - (y - 8)² - 2x - 1
∴ x² = 8 - (y - 8)² - 2x
OR:
∵ x² = 8 - (y² -16y + 64) - 2x
∴ x² = 8 - y² + 16y - 64 - 2x
∴ x² = 16y - y² - 2x - 56
You must factor.

The factored form is equal to the assigned form.

Values a, b correspond to the factored 1, -1.
Value of x however remains unknown. But we can change that.
Given factored result,

We can set expression equal to 0 then find such x that when added with number a or b results with 0.

Hence x has 2 solutions.

Hope this helps.
