      Hi!


      You have:

      $$4a^2-9$$


      You can use the difference of squares technique to find the factors of this expression:

      $$(2a)^2-3^2$$

      $$(2a-3)(2a+3)


      So the factors are (2a-3) and (2a+3). The sum of these factors is:

      $$(2a-3)+(2a+3)$$

      $$2a-3+2a+3$$


      I'll let you do the maths ;)


      Reach out if there is anything else! 😁
