    • Which of the following are true ?
a)
If p(x) is divided by (x - a), the remainder is p(a)
b)
If p(a) = 0, then (x + a) perfectly divides p(x)
c)
If the degree of p(x) is less then the degree of d(x), we should not divide p(x) with d(x)
d)
Division of a polynomial with another polynomial stops when the degree of the remainder equals the degree of the divisor
