Question

The value of k when u +1 is a factor ax3 + 9x² - 5x+k is_____​

Answer 1

Step-by-step explanation:

To find f(k) , determine the remainder of the polynomial f(x) when it is divided by x−k . k is a zero of f(x) if and only if (x−k) is a factor of f(x) . Each rational zero of a polynomial function with integer coefficients will be equal to a factor of the constant term divided by a factor of the leading coefficient.
