Answer 2

To simplify the given expression, let's start by expanding the square term:

(2x - 5)^2 = (2x - 5) * (2x - 5) = 2x * 2x - 2x * 5 - 5 * 2x + 5 * 5 = 4x^2 - 10x - 10x + 25 = 4x^2 - 20x + 25

Now, we can substitute this back into the original expression:

2 * (4x^2 - 20x + 25) + 40

Next, distribute the 2 across the terms inside the parentheses:

2 * 4x^2 + 2 * (-20x) + 2 * 25 + 40

Simplify further:

8x^2 - 40x + 50 + 40

Finally, combine like terms:

8x^2 - 40x + 90

So, the simplified expression is 8x^2 - 40x + 90.
