Provide an appropriate response.A student is trying to solve the equation (x + 4)(x - 4) = 7. The student has set x + 4 = 7 and x - 4 = 7 and found that two solutions x = 3, x = 11. The student checks her results by plugging in her solutions into the original equation and finds that they do not work. How would you advise her?
What will be an ideal response?
The equation needs to be set to zero in order to use the principle of zero products.
