Question

Que 14 What will be the value of Discriminant of Quadratic equation having two real
and Distinct roots?​

Answer 1

A quadratic equation, ax2 + bx + c = 0; a ≠ 0 will have two distinct real roots if its discriminant, D = b2 - 4ac > 0.

Answer 2

Answer:

PLZ MARK AS BRAINLIEST !

Step-by-step explanation:

A quadratic equation, ax2 + bx + c = 0; a ≠ 0 will have two distinct real roots if its discriminant, D = b2 - 4ac > 0.

(i) FOR EXAMPLE - Given equation is x2 – 3x + 4 = 0

On comparing with standard equation we have,

a = 1, b = –3 and c = 4

Now, D = b2 – 4ac = (–3)2 –4(1) (4) = 9 – 16 = – 7< 0

Hence, the equation x2 –3x + 4 = 0 has no real roots.
