Question

x^2+kx-19 find alll the values of k so that the trinomial can be factored using intergers

Answer 1

lets see what the answer is

Answer 2

-19
-19 and 1 are factors of -19
so we need k=-19+1=-18

Answer 3

or -19
19 and -1 are factors of -19
so k needs to be 19-1=18

Answer 4

two options

Answer 5

lol

Answer 6

x^2-18x-19
(x-19)(x+1)
-------------

x^2+18x-19
(x+19)(x-1)

Answer 7

k could alo be -18

Answer 8

also !!

Answer 9

yes it cool only be -18 or 18

Answer 10

Are you sure k=18 works?

Answer 11

(x+19)(x-1)

Answer 12

yes (x + 19)(x - 1) = x^2 + 18x - 19
