Question

Find the values of k that make 2x^2 + kx + 5 factorable.

Answer 1

use quadratic formula

Answer 2

@ksaimouli wtf is that

Answer 3

okay not introduced dont worry

Answer 4

what is 2*5

Answer 5

10

Answer 6

yup so what r some multiples

Answer 7

of 10

Answer 8

Well I know like how to factor an polynomial like that but not how to find a variable in one

Answer 9

lets say these for now 5 and 2

Answer 10

add 5+2=7 so the variable is 7

Answer 11

wait so then k would be 7

Answer 12

yup

Answer 13

there are 3 more possible answers, so keep that in mind

Answer 14

that if one of them

Answer 15

if->is

Answer 16

So it would be 7 or 11

Answer 17

good, then -7 and -11 are the other two because

2x^2 - 7x + 5

and

2x^2 - 11x + 5

are both factorable

Answer 18

since -2 + (-5) = -7 and -1 + (-10) = -11
