Question

What are the linear factors of equation x2 +kx +1=0 ?​

Answer 1

Answer:

k=2

Step-by-step explanation:

D=bsquare-4ac

D=ksquare-4.1.1

D=ksquare-4k

ksqyare-4=0

ksquare=4

k=4

Answer 2

Answer:

a = 1

b = k

c = 1

By method of discriminant,

b^2 - 4ac

k^2 - 4 (1)(1)

k^2 = 4

k = 2
