Provide an appropriate response.Which of the following equations is not in proper form for using the zero-factor property? Explain your answer.-7r(r - 4)(r - 3) = 0z(10z - 1) = 0z(z - 2) + 2(z - 4) = 0(z - 1)(z - 2) = 0
What will be an ideal response?
z(z - 2) + 2(z - 4) = 0. This is not in proper form because the left side is not written as a product.
