Answer 2

To simplify the expression (x - 5)² + 2x(x - 3), you can follow these steps:

1. Expand the squares:

(x - 5)² = (x - 5)(x - 5) = x² - 10x + 25

2. Expand 2x(x - 3):

2x(x - 3) = 2x² - 6x

3. Now, add the two simplified expressions together:

(x - 5)² + 2x(x - 3) = (x² - 10x + 25) + (2x² - 6x)

4. Combine like terms by adding the coefficients of x², x, and the constants:

x² + 2x² - 10x - 6x + 25 = 3x² - 16x + 25

So, (x - 5)² + 2x(x - 3) simplifies to 3x² - 16x + 25.
