Question

deteminate the polynomial if so it gets a factor x-k

x^2-7x+12

Answer 1

are you familiar with remainder theorem?

Answer 2

i guess nobody's home

Answer 3

yes

Answer 4

x - k is a factor therefore p(k) = 0

p(x) = x^2 - 7x + 12
p(k) = k^2 - 7k + 12

therefore we just equate that to 0

k^2 - 7k + 12 = 0
(k-4)(k-3) = 0

therefore your possible roots are k = 4 and k = 3

Answer 5

does that help/
