Solution:

√36 - x^2 = 3
36 - x^2 = 3^2
36 - x^2 = 9
x^2 = 27
x = ±√27

√7 - x^2 = √-6x
7 - x^2 = -6x
x^2 - 6x - 7 = 0
(x-7)(x+1) = 0
x = 7 or x = -1

(2x-3)√(2x^2-5x+2) = 0
Setting each factor equal to zero:
2x - 3 = 0
2x = 3
x = 3/2

√(2x^2 - 5x + 2) = 0
2x^2 - 5x + 2 = 0
(2x-1)(x-2) = 0
x = 1/2 or x = 2

Combining the solutions, we have x = 3/2, 1/2, 2.

Therefore, 12 * 2 = 24.
