Given the equation:

x=√-5x-6

Prove that the given equation has no solution.

Explanation:

The given equation has no solution, since the equation is composed of negative values. We know that negative numbers cannot be squared, since any number that is raised to 2 or squared cannot result to a negative number, due to the fact the similar signs will result to a positive number. Hence, taking the square root of a negative number, will result to an imaginary number or a complex number, which can be denoted by the sign i.
