(6x-1)(6x+1)-4x(9x+2)=-1

To solve the equation, we can start by expanding both sides:

(6x-1)(6x+1)-4x(9x+2) = -1

Expanding the left side:

(36x^2 - 1) - (36x^2 + 8x) = -1

Now, combine like terms:

36x^2 - 1 - 36x^2 - 8x = -1

Simplifying further:

-1 - 8x = -1

Now, isolate the variable:

-8x = 0

Dividing both sides by -8:

x = 0

So, the solution to the equation is x = 0.
