-4root%284%2C3x%2B6%29=12
root%284%2C3x%2B6%29=-3
3x+6 = 81
x = 25

That's because there is NO SOLUTION.

Think about this! - 4 * - 3 = + 12. But, can root%284%2C3x%2B6%29 equal - 3? I think not!!

Or, ask yourself this, "Is there a REAL number that when you take the 4th root of it, the result is - 3?"
