Let's simplify the left side of the equation first:

(6z-2)(2z+3) - 3z(2z-7)
= 12z^2 + 18z - 4z - 6 - 6z^2 + 21z
= 6z^2 + 35z - 6z - 6
= 6z^2 + 29z - 6

Now, let's compare this to the right side of the equation (which is 29 + 6z^2):

6z^2 + 29z - 6 = 29 + 6z^2

Since the left side is equal to the right side, the equation is verified.
