In this chapter, you’ll study about complex numbers and quadratic equations. Complex Numbers are a combination of real numbers and imaginary numbers. A complex number can be written in the form a + bi where ‘a’ and ‘b’ are real numbers (also 0) and ‘i’ is an imaginary number.
A Quadratic Equation is an equation having the degree ‘2’. You’ll also learn about the quadratic formula and fundamental theorem of algebra, algebraic properties, argand plane, polar representation of complex numbers, square root of a complex number and much more in NCERT Solutions for Class 11 Maths, Chapter 5.
It is interesting to know that complex numbers and quadratic equations are used in varied fields such as electrical engineering, physics while launching a satellite and more. So, in-depth knowledge of this topic is quite helpful to you!
