Match the column
 type of polynomial Polynomial monomial x5 -3x2 +1 binomial x-1 trinomial x4-3x2+2+ 3x3 No appropriate match x2 -2x-1 3x3
Table Type
P(x)=5x2 -3x+7
 P(0) P(1) P(5) P(-1) P(-2)
Multiple choice Questions
1) Find the remainder  when x4+x3-2x2+x+1 is divided by x-1 a)1
b)5
c)2
d)3
Solution ( c)
2) Which of these identities is not true? Solution (d)
True or False statement
1. P(x) =x-1 and g(x) =x2-2x +1 .  p(x) is a factor of g(x)
2. The factor of 3x2 –x-4 are  (x+1)(3x-4)
3. Every linear polynomial has only one zero
4. Every real number is the zero’s of zero polynomial
5. A binomial may have degree 4
6. 0,2 are the zeroes of x2-2x
7. The degree of zero polynomial is not defined

Solution
1. True, as g(1)=0
2. True, we can get this by split method

3. x3-23x2+142x-120
4. 1+8x3
Solution
a)     (x+6)(x+3)
b) )(3x-1)(x-1)(x+1)
c)(x-1)(x-10)(x-12)
d) (2x+1)(4x2-2x+1)

Reference Books for class 9 Math

Given below are the links of some of the reference books for class 9 Math.

1. Mathematics for Class 9 by R D Sharma One of the best book for studying class 9 level mathematics. It has lot of problems to be solved.
2. Secondary School Mathematics for Class 9 by R S Aggarwal This is also as good as R.D. Sharma. Either this or the book by R.D. Sharma will do. I find book R.S. Aggarwal little bit more challenging than the one by R.D. Sharma.
3. Pearson IIT Foundation Series - Maths - Class 9 Buy this book if you want to challenge yourself further and want to prepare for JEE foundation.
4. Pearson IIT Foundation Physics, Chemistry & Maths combo for Class 9 Only buy if you are prepared to study extra topics and want to take your studies a step further. You might need help to understand topics in these books.

You can use above books for extra knowledge and practicing different questions.
