concept map of chapter polynomial of class 9
Answers
Answer:
VARIABLE:- Alphabetically letters[a-z]
CONSTANT TERM:- Fixed term[1,2,3,...]
ALGEBRAIC EXPRESSIONS:- The combination of variable and constant term with any mathematical sign. Ex:- 2+4x, 2x, etc....
POLYNOMIAL
An algebraic expressions will be polynomial if:
1. Variable should be root free or redical free. Ex:- √2x³(Not Polynomial), 5x-6(Polynomial), etc....
2. Powers of variable should not be in negative form or fractional part. Ex:- x⅔-2x-5(Not Polynomial), x²+2x+9(Polynomial).
3. Variable should not be in fractional part and not in denominator.
After fifth pic, other left written work is given below:-
=a²-ab+ac-ab+b²-bc+ac-bc+c².
=a²+b²+c²-2ab-2bc+2ca
7. (a-b-c)² = a²+b²+c²-2ab+2bc-2ca
=(a-b-c) × (a-b-c)
=a²-ab-ac-ab+b²+bc-ac+bc+c²
=a²+b²+c²-2ab+2bc-2ca.
"IF YOU PREPARE ALL THESE TOPICS AND FARMUALS, THEN DEFINITELY YOU WILL BE ABLE TO HANDLE ALL QUESTIONS OF CHAPTER-2, POLYNOMIAL."
"I recommend you to please understand my given concept map of chapter-polynomial and then try to do it by yourself and prepare all the farmulas by understanding it not directly copying from my given concept map."
