To solve this quadratic equation, we can first factor out an x:

x(x^2 - 7x - 46) + 324 = 0

Now, we need to factor the quadratic trinomial x^2 - 7x - 46:

(x - 11)(x + 4) + 324 = 0

Now we have:

(x - 11)(x + 4) = -324

To find the values of x, we set each factor to zero:

x - 11 = 0 or x + 4 = 0

x = 11 or x = -4

Therefore, the solutions to the equation Xxx-7xx-46*x+324=0 are x = 11 and x = -4.
