Factorise everything u can then multiply the fractions then cancel common factors

(2x+3)(2x-3)/3(2x+3) is the first fraction

#

so that's (2x-3)/3

i got until 2x(4x^2 -9)/3x(2x^2-3x-9)

tall token i got until 2x(4x^2 -9)/3x(2x^2-3x-9)

There's difference of 2 squared

#

There is an identity for a general expression in the form (a^2 - b^2)

#

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

#

The numerator of the first fraction is in that form

#

Where a = 2x and b = 3
So you can factorise the numerator of the first fraction to be (2x + 3)(2x - 3)

#

Because if you expand that out you will get:
4x^2 - 9
