$= 9 x^{2} - 4$ $= 9x^2 - 4$

$(3 x + 2) (3 x - 2)$ $(3x+2)(3x-2)$

Applying the below mentioned property we can simplify the expression:
$(a + b) (a - b) = a^{2} - b^{2}$ $color(blue)((a+b)(a-b)= a^2 - b^2$

Here : $a = 3 x, b = 2$ $color(blue)(a=3x , b=2$

$(3 x + 2) (3 x - 2) = {(3 x)}^{2} - 2^{2}$ $(3x+2)(3x-2) = color(blue)((3x)^2 - 2^2$

$= 9 x^{2} - 4$ $= 9x^2 - 4$

How do you simplify (3x + 2)(3x - 2) (3x+2)(3x−2)(3x + 2)(3x - 2) ?
