Answer 2

Given polynomial: 2x² + x - 4 = 0

Here,

• a = 2
• b = 1
• c = - 4

D = b² - 4ac

⇒D = (1)² - 4(2)(-4)

⇒D = 1 - (-32)

⇒D = 1 + 32

⇒D = 33

Since the value of Discriminant is greater than 0, it has 2 roots which are real and Unequal.

Additional information:

1. Discriminant is the number that denotes the real solutions of a quadratic equation. It is represented by D
2. If D = 0, the Equation would be having 1 real root which is repeated
3. If D > 0, it means that the equation has no real roots.
