This is an example of sum and difference of two squares.
Just get the square root of each term
(3a - 8b) (3a + 8b)

9a^2 - 64b^2 = (3a + 8b) (3a - 8b)

9a^2 - 64b^2
=(3a + 8b) (3a - 8b)

9a^2-64b^2=(3a)^2-(8b)^2=(3a-8b)(3a+8b)

hi
you know (a+b)*(a-b)=a^2-b^2
so 9a^2=(3a)^2,
64b^2=(8b)^2
so (3a)^2-(8b)^2=(3a+8b)(3a-8b)
bye

isn't it (3a-8b)(3a+8b) ?
