Provide an appropriate response.In working the problem x2 = 4x, Sharon began by dividing both sides of the equation by x to get the new equation x = 4. What, if anything, is wrong with this method?

What will be an ideal response?


By dividing both sides of the equation by the variable, Sharon lost one of the solutions to the equation. The lost solution should be x = 0, which would make the equation undefined.
