Answer 2

To simplify the expression (5a-2b)(5a+2b)-10ac+c^2, you can use the distributive property to expand and then combine like terms. Here's the step-by-step simplification:

1. Start by expanding the first part of the expression: (5a - 2b)(5a + 2b) = 25a^2 - 4b^2.

2. Now, combine the expanded expression with the remaining terms: (25a^2 - 4b^2) - 10ac + c^2.

3. Next, combine like terms, which are the constants (-4b^2, -10ac, and c^2): 25a^2 - 4b^2 - 10ac + c^2.

This is the simplified form of the given expression.
