Answer 2

To simplify the given expression, follow the steps below:

Step 1: Distribute the terms inside the brackets. Step 2: Combine like terms.

Let's begin:

(-8a + 9b) * (-4a + 8b) + (8a + 3b) * (-a + 8b)

Step 1: Distribute the terms inside the brackets:

(-8a * -4a) + (-8a * 8b) + (9b * -4a) + (9b * 8b) + (8a * -a) + (8a * 8b) + (3b * -a) + (3b * 8b)

Step 2: Multiply the terms:

(32a^2) + (-64ab) + (-36ab) + (72b^2) + (-8a^2) + (64ab) + (-3ab) + (24b^2)

Step 3: Combine like terms:

Combine the terms with the same variables raised to the same powers:

(32a^2 - 8a^2) + (-64ab - 36ab + 64ab - 3ab) + (72b^2 + 24b^2)

Simplify:

24a^2 - 39ab + 96b^2

So, the simplified expression is:

24a^2 - 39ab + 96b^2
