Answer 2

The equation you provided is in the form of a quadratic equation. Let's break it down step by step:

y = 3(x - 5)²

To simplify, let's expand the squared term:

y = 3(x - 5)(x - 5)

Using the distributive property, we can multiply each term:

y = 3(x² - 10x + 25)

Now, distribute the 3 to each term inside the parentheses:

y = 3x² - 30x + 75

So, the expanded form of the equation y = 3(x - 5)² is y = 3x² - 30x + 75.
