Question

x square + 3 x +8 =0 find discriminant​

Answer 1

Answer :

x² + 3x + 8 = 0

On comparing it with the standard form of quadratic equation ax² + bx + c = 0, we get -

a = 1, b = 3, c = 8

Discriminant = b² - 4ac

⇒ D = (3)² - 4 * 1 * 8

⇒ D = 9 - 32

⇒ D = -23

∴ D < 0

Given =>

A = 1

B = 3

C = 8

*******

D = B² - 4AC

D = 3² - 4 × 1 × 8

D = 9 - 32

D = - 23

D < 0

Hence , quadratic equation has No real roots
