CBSE Class 9 - Real Numbers - Problem on Rationalisation (Part-3)

The video series provides solutions for typical problems related to rationalization of irrational numbers covered under chapter real numbers. The video covers the solution for a long type of answer based question.

If the denominator of an expression is a surd, it can be reduced to an expression with rational denominator.

If the product of two surds is a rational number, then each one of them is a rationalizing factor of the other.

In this series, we'll try to present solutions for more HOTS and typical problems.

Class 9 - Maths - Real Numbers - Problems on Rationalization (Part-2) For CBSE students

The video series provides solutions for typical problems related to rationalization of irrational numbers covered under chapter real numbers. The video covers the solution for a long type of answer based question.


If the product of two irrational numbers is a rational number, then each number is called the rationalization factor. The process of multiplying an irrational number by its rationalising factor is called rationalisation. In this series, we'll try to present solutions for more HOTS and typical problems.

Typical Factorisation Solved Problems

Class 8/9/10 - Mathematics

Q1: Factorise x⁴ + x² + 1

Answer: x⁴ + x² + 1

= (x⁴ + 2x² + 1) - x²

Using identity (A + B)² = A² + B² + 2AB

= (x² + 1)² - x²

Using identity A² - B² = (A + B)(A - B)

= (x² + 1 + x)(x² + 1 - x) [Answer]
