Solution (d)
True or False statement

P(x) =x-1 and g(x) =x²-2x +1 . p(x) is a factor of g(x)
The factor of 3x² –x-4 are (x+1)(3x-4)
Every linear polynomial has only one zero
Every real number is the zero’s of zero polynomial
A binomial may have degree 4
0,2 are the zeroes of x²-2x
The degree of zero polynomial is not defined

Solution

True, as g(1)=0
True, we can get this by split method
True
True
True , example x⁴ +1
True
True

Reference Books for class 9 Math

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

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.
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.
Pearson IIT Foundation Series - Maths - Class 9 Buy this book if you want to challenge yourself further and want to prepare for JEE foundation.
