Question

the value of k for which (- 4) is zero of the polynomial X^2 -x-(3k + 2).Find k

Answer 1

Answer:

K = 6

Step-by-step explanation:

P(x) = x² - x - (3k + 2)

P(-4) = (-4)² - (-4) - (3k + 2) = 0       {Given}

       = 16 + 4 - (3k + 2) = 0

Hence, 20 = 3k + 2

             18 = 3k

              k = 6
