Checking the options against the second equation x^2 - sqrt(2x^2 - 8x + 12) = 4x + 6 reveals that x = -2 is a solution. Substituting x = -2 yields (-2)^2 - sqrt(2(-2)^2 - 8(-2) + 12) = 4(-2) + 6, which simplifies to 4 - sqrt(16 + 16 + 12) = -8 + 6. This results in 4 - 6 = -2, which confirms the value.
