Question

please answer guys need help​

Answer 1

Answer:

a = 2

Step-by-step explanation:

• Zeroes of a polynomial are the values of x which satisfy the given condition.

• To check whether or not some values satisfy the condition, put the value of the function equal to zero.

In the question,

Since -1 is a zero of the polynomial, on placing its value we can get the value of p(x) as 0.

=> p(x) = ax³ - x² + x + 4

=> 0 = a(-1)³ - (-1)² + (-1) + 4

=> 0 = -a - 1 - 1 + 4

=> 0 = -a + 2

=> a = 2

Therefore, the value of a is 2.
