Question

DUM HAI TO KARO................

Answer 1

the numbers which when put at place of x give polynomial=0 are 1

now the divider of the polynomial are (x-1) ,

so we can say that (x-1) is divider of polynomial.

so when we divide we get....
p(x)=(x-1)(2x^3+2x^2-11x+15)
p(x)=(x-1)(x+1)(x+3)(x+5)

because factorials of 15=1,3,5
