Question

Fir what value of k( -4) is a zero of the polynomial x²-2x(7p+3)​

Answer 1

Answer:

Where is the k inside the given question..

Step-by-step explanation:

I think p is written there instead of k.

p(x) = x² - 2x(7k + 3)

p(-4) = (-4)² -2(-4)(7k+3)

  0  = 16 +8(7k+3)

  0 = 16 + 56k + 24

56k = - 40

  k = -40/56

   k = -5/7
