  • 4.4 Solution of a Quadratic Equation by Completing the Square
  • 4.5 Nature of Roots

There are 4 exercises covering the above topics. The solution of Chapter 4 exercises can be found in this link.

SEBA CLASS 10 MATHS CHAPTER 4 (QUADRATIC EQUATIONS)

A quadratic equation is a type of polynomial equation of degree 2. The standard question of an quadratic equation that can be written in the form:

ax2 + bx + c = 0

where a, b, and c are constants and x is a variable. 

Quadratic equations can have zero, one, or two solutions, depending on the values of the constants a, b, and c.

SOLVING QUADRATIC EQUATIONS

To solve a quadratic equation, you can use the quadratic formula:

x = (-b +/- sqrt(b2 – 4ac)) / (2a)

where sqrt(b2 – 4ac) is the square root of (b2 – 4ac).

For example, to solve the quadratic equation x2 + 4x + 3 = 0, you would plug the values a=1, b=4, and c=3 into the quadratic formula:

x = (-4 +/- sqrt(42 – 4*1*3)) / (2*1)

x = (-4 +/- sqrt(16 – 12)) / 2

x = (-4 +/- sqrt(4)) / 2

x = (-4 +/- 2) / 2

x = -3 or x = -1

So, the solutions to the equation x2 + 4x + 3 = 0 are x = -3 and x = -1.
