29. Which of the following expressions is a factor of the polynomial x^2-x-72 A. x-9 B. x-8 C. x+2 D. x+9 E. x+36

Question

Answer 1

To determine which of the given expressions is a factor of the polynomial

, we need to factor the polynomial.First, we look for two numbers that multiply to

and add up to

. These numbers are

and

, since:

Thus, we can factor the polynomial as:

Now, we check which of the given options are factors:-

-

From our factorization, we see that the factors are

and

.Therefore, the correct answers are:A.

B.
