Provide an appropriate response.A student is trying to solve the equation (x + 3)(x - 6) = 7. The student has set x + 3 = 7 and x - 6 = 7 and found that two solutions x = 4, x = 13. The student checks his or her results by plugging in his or her solutions into the original equation and finds that they do not work. How would you advise him or her?
What will be an ideal response?
The equation needs to be set to zero in order to use the zero-factor theorem.
