Empty Set: 
A set is said to be empty set if it does not have any element. It is denoted by Φ or {}. Empty set is also called a null set or void set.
For example, The set of all odd natural numbers divisible by 2 is an empty set because odd natural numbers are not divisible by 2.

Finite Set: 
A set which contains finite number of elements is called a finite set.
For example, The set {x: x ∈  N and x ≤ 10} is a finite set because number of elements in the set are countable.

Acids are the substances which taste sour, change blue litmus red, are corrosive to metals and furnish H⁺ ions in their aqueous solutions.

Bases are the substances which taste bitter, change red litmus blue, feel slippery and furnish OH⁻ ions in their aqueous solutions.

Acid-base indicators are dyes or mixtures of dyes which are used to indicate the presence of acids and bases.

Indicators are the substances that show one colour in an acidic medium and another colour in a basic medium. Litmus, phenolphthalein and methyl orange are commonly used indicators. Onion, Vanilla extract and Clove oil are olfactory indicators.

Typical Factorisation Solved Problems

Class 8/9/10 - Mathematics
CBSE Class 8/9/10 - Mathematics - Typical Factorisation Solved Problems (#class8Maths)(#cbsenotes)(#eduvictors)

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]

निम्नलिखित गद्यांश को ध्यानपूर्वक पढ़कर नीचे दिए गए प्रश्नों के उत्तर दीजिए :

संसार के सभी धरम धर्मों में एक बात समान है, वह है प्रार्थना, ईश्वर भक्ति। प्रार्थना द्वारा हम अपने हदय के भाव प्रभु के सम्मुख रखते हैं और कुछ न कुछ उस शक्तिमान से माँगते हैं। जब हमें मार्ग नहीं सूझता तो हम प्रार्थना करते है। प्रार्थना का फल उत्तम हो, इसके लिए हम अपने अंदर उत्तम विचार और एकाग्र मन उत्पन्न करने होते हैं, क्योंकि विचार ही मनुष्य को पीड़ा पहुँचाते हैं या उससे मुक्त करते है। हमारे विचार ही हमे ऊँचाई तक ले जाते हैं या फिर खाई में फ़ेंक देते हैं। यह मन ही हमारे लिए दुःख लाता है और यही आनंद की ओर ले जाता है। यजुर्वेद के एक मंत्र के अनुसार यह मन सदा ही प्रबल और चंचल है। यह जड़ होते हुए भी सोते - जागते कभी भी चैन नहीं लेता। जितनी देर हम जागते रहते है, उतनी देर यह कुछ न कुछ सोचता हुआ भटकता रहता है। अव प्रश्न यह उठता है कि मन जो अत्यंत गतिशील है, उसको स्थिर और वश में कैसे किया जाए। मन को वश मे करने का यह तात्पर्य नहीं कि यह गतिहीन हो जाए और यह गतिहीन हो ही नहीं सकता। जिस प्रकार अग्नि का धर्म ऊष्ण है उस परकार चंचलता मन का धर्म है|
