Expanding the given expression:

(×'2 + × - 2)(×'2 + × - 3)
= ×'2 ×'2 + ×'2 × - ×'2 3 + × ×'2 + × × - × 3 - 2 ×'2 - 2 × - 2 * 3
= ×'4 + ×'3 - 3×'2 + ×'2 + ×'2 - 3× - 2×'2 - 2× - 6
= ×'4 + ×'3 - 2×'2 + ×'2 + ×'2 - 3× - 6
= ×'4 + ×'3 - ×'2 - 3× - 6

For the expression to equal 12, we need to solve the equation:

×'4 + ×'3 - ×'2 - 3× - 6 = 12

However, this equation involves powers of unknowns, and it may not have an exact solution. This requires further analysis or approximation methods to find the roots of the equation.
