Kiran saw that if the equation (x + 2)(x - 4) = 0 is true, then, by the zero product property, either X + 2 is 0 or X - 4 is 0. He then reasoned that, if (x + 2)(x -
4) = 72 is true, then either x + 2 is equal to 72 or X-6 is equal to 72.
Explain why Kiran's conclusion is incorrect
Kiran is incorrect because the
product property only applies to products that are equal to
not ahoy product. Many pairs of factors can be multiplied to be 72. We can't be sure that one of the
factors is equal to 72
