Provide an appropriate response.A student says that the equation  can be solved as follows: y - 4 = 1 or y + 5 = 5. If this is correct, explain why. If it is not correct, explain why and give the correct method.

What will be an ideal response?


This is not correct. The zero-factor property only works when the right side of the equation is zero. The left side of the equation must be expanded and -5 must be added to both sides of the equation in order to make the right side equal to zero. Then the left side may be factored, and the zero-factor property applied.
