Question

if the
equation x² - bx + 1=0
has two distinct real roots
then
the following
14
correct
​

Answer 1

Step-by-step explanation:

for 2 distinct real roots of a quadratic equation,

the Discriminant (D) dhold be greater than 0

D = b²-4ac

0 < D

= 0 < b² - 4(1) (1)

= 0 < b² -4

= 4 < b²

-----> b>4 or b <-4

b = (-∞,-4) U (4,∞)
