Answer
$$2x(3y + 2)(3y - 2)$$
Work Step by Step
We see from the binomial that we can factor out an $2x$ from both terms to simplify it:
$$2x(9y^2 - 4)$$
We see now that we have the difference of two squares, so we use the following formula:
$$A^2 - B^2 = (A + B)(A - B)$$
For this binomial, we take the square root of the leading term $(9y^2)$ to get $A = 3y$ and the square root of the second term $(41)$ to get $B = 2$.
So we now plug these two values into the formula for factoring the binomial:
$$2x(3y + 2)(3y - 2)$$
