Topics Covered in Exercise 4.3 Class 10 Mathematics Questions
Here are the topics you need to know about covered in the ex 4.3 class 10 maths.
1. 
Nature of Roots 
 Nature of Roots  Nature of roots depends on the discriminant of the quadratic equation. The discriminant of the quadratic equation is defined by b24ac.
Quadratic Formula  The roots of a quadratic equation ax2 + bx + c = 0 are given by
x = [b ± √(b2  4ac)] / 2a, provided b24ac ≥ 0
b2 – 4ac determines whether the quadratic equation ax2 + bx + c = 0 has real roots or not, b2 – 4ac is called the discriminant of this quadratic equation.
Important Points
Based on the discriminant value, b2+4ac, it can be determined that the quadratic roots of the equation ax2+bx+c = 0 can have three different types.

if b2 – 4ac > 0, then the equation has two distinct real roots

if b2 – 4ac = 0, then the equation has two equal real roots

if b2 – 4ac < 0, then the equation has no real roots
