Answer 2

36a+48ab-48ab-64b²-36a²=36a²-64b²-36a²=-64b²

Answer 3

To simplify the expression (6a-8b)(6a+8b)-36(aa), follow these steps:

Step 1: Expand the expression using the distributive property. Step 2: Simplify the terms. Step 3: Factorize, if possible.

Let's start:

Step 1: Expand the expression using the distributive property: (6a - 8b)*(6a + 8b) - 36(a^2)

Expanding the first part: = 6a * 6a + 6a * 8b - 8b * 6a - 8b * 8b - 36(a^2)

Step 2: Simplify the terms: = 36a^2 + 48ab - 48ab - 64b^2 - 36(a^2)

Step 3: Combine like terms: = 36a^2 - 36a^2 - 64b^2

Step 4: Simplify further: = 0 - 64b^2

Step 5: The final simplified expression is: = -64b^2

So, (6a-8b)(6a+8b)-36(aa) simplifies to -64b^2.
