Finding the root is not the existence of the equation itself, but the unreasonable method of solving the equation. It is not necessarily unsolvable to solve the original equation of increasing roots by solving the equation. This equation has no solution and does not necessarily have increasing roots. For example, if 5/X=5/(X+2) has no solution, solving the equation in a general way will not produce root growth. (In fact, according to the fact that the numerator is equal to or not equal to 0 and the denominator is not equal to 0, we can directly draw the conclusion that the equation has no solution. )
