Answer: The answer to this question is (2a-5)(2a+5)

Explanation:

  • Because first, you have to write the quadratic equation 4a^2-25 in exponential form

  • Then, you calculate the product by multiplying the terms with equal exponents by multiplying their bases

(2a)^2-5^2

  • And then last but not least, using a^2-b^2=(a-b)(a+b), factor the expression

(2a-5)(2a+5) and then there's your answer and your explanation!!!!!
