Answer:
Option (4)
Step-by-step explanation:
If a quadratic equation is represented by,
ax² + bx + c = 0
Then discriminant of this equation will be = b²- 4ac
Discriminant of a quadratic equation tells the type of roots the equation has.
1). If b² - 4ac > 0,
Equation will have two distinct real roots
2). If b² - 4ac = 0
Equation will have one real root
3). If b² - 4ac < 0
Equation will have no real roots or there will be two imaginary roots.
For two real roots,
b² - 4ac > 0
b² > 4ac
Therefore, Option (4). 4ac < b² will be the answer.
