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
