Answer 2

Answer: 24a

if helpful mark as brainliest answer :)

Step-by-step explanation:

a^2-b^2 = (a+b)(a-b)

here a =[2a+3]

        b =[2a-3]

therefore [2a+3]²-[2a-3]² = (2a+3+2a-3)(2a+3-(2a-3))

                                          = (4a)(2a+3-2a+3)

                                          = (4a)(6)

                                           =24a//
