A.
B.
Table Type
P(x)=5x
^{2} -3x+7
Multiple choice Questions
Question 1

^{4}+x
^{3}-2x
^{2}+x+1 is divided by x-1
(a)1
(b)5
(c)2
(d)3
Solution
( c)
Question 2
Which of these identities is not true?
Solution
(d)
True or False statement
- P(x) =x-1 and g(x) =x^{2}-2x +1 . p(x) is a factor of g(x)
- The factor of 3x^{2} –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 x^{2}-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 x^{4} +1
- True
- True
Question
