Question

for what value of k,-4 is a zero of the polynomial x square-x-(2x-2)​

Answer 1

Step-by-step explanation:

Given: -4 is one of zeroes of the polynomial x2 ‒ x- (2k + 2),

which means x = -4

will satisfy it. x2 – x – (2k + 2) = 0 (-4)^2 – (-4) – 2k – 2 = 0 16 + 4 – 2k – 2 = 0 -2k + 18 = 0 k = 9

The value of k is 9.
