How do you solve 16a2-4b2?

Answer 1

To solve the expression (16a^2 - 4b^2), you can factor it using the difference of squares formula, which states that (x^2 - y^2 = (x - y)(x + y)). Here, you can rewrite (16a^2) as ((4a)^2) and (4b^2) as ((2b)^2). Thus, the expression factors to ((4a - 2b)(4a + 2b)).
