The value of k for which (-4)is a zero of the polynomial x square -x-(2k-2) is About the author Jasmine
[tex]x – 4 = 0 \\ x = 0 + 4 \\ x = 4 \\ {x }^{2} – x – (2k – 2) = 0 \\ {4 }^{2} – 4 – (2k – 2) = 0 \\ 16 – 4 – 2k + 2 = 0 \\ 12 – 2k + 2 = 0 \\ 14 – 2k = 0 \\ – 2k = – 14 \\ k = \frac{ – 14}{ – 2 } \\ k = \frac{14}{2} \\ k = 7[/tex] Reply
