A.
Jamal is correct because is equivalent to .

B.

C.

D.
Jamal is incorrect because is equivalent to .

Answer 1

To determine whether Jamal is correct or incorrect in finding the zeros of the equation, we need to know the equation he factored and the specific values he concluded for the x-intercepts. However, since the equation and the values are not provided in your question, we can't definitively answer which statement is correct.

In general, when analyzing whether a person's conclusion about the zeros (or x-intercepts) of a factored equation is accurate, it is essential to verify:

1. The factors that were used.
2. The calculations involved in finding the zeros.
3. Whether the conclusion about the intersection with the x-axis is correct based on those factors.

If the factored form of the equation he worked with correctly reflects the roots, then he is correct; otherwise, he may be incorrect.

If you provide the original equation or the specific x-intercepts Jamal concluded, I would be able to offer a more accurate assessment and select the correct option among A, B, C, or D.
