Answer 2

The expression you provided is a quadratic equation in two variables, x and y. Let's break it down:

(x + 1)² + (y - 4)² - 16

Expanding the equation:

(x + 1)² = (x + 1)(x + 1) = x² + 2x + 1

(y - 4)² = (y - 4)(y - 4) = y² - 8y + 16

Now substituting these expanded expressions back into the original equation:

x² + 2x + 1 + y² - 8y + 16 - 16

Combining like terms:

x² + 2x + y² - 8y + 1

So, the expanded form of the expression (x + 1)² + (y - 4)² - 16 is x² + 2x + y² - 8y + 1.
