1.	5. Discriminant(D) of thequadratic equation x2 +31=0 is124- 1 240None of these
Answer» ANSWER: Step-by-step explanation: x² + 31 = 0 or, x² + 0 X + 31 = 0 Here, a = 1, b = 0, c = 31 So, D = b² - 4 a c = 0² - 4 × 1 × 31 = 0 - 124 = - 124 HENCE, option (b) - 124 Plz mark as brainliest.

Answer»

ANSWER:

Step-by-step explanation:

x² + 31 = 0

or, x² + 0 X + 31 = 0

Here, a = 1, b = 0, c = 31

So,

D = b² - 4 a c

= 0² - 4 × 1 × 31

= 0 - 124

= - 124

HENCE, option (b) - 124

Plz mark as brainliest.
