(Q2) Verify that the numbers given along side the cubic polynomial below are their zeros.Also verify the relationship between the zeros and the coeffcients in each case
x3+4x2+5x-2;(1,1,1)
Answer:
Given polynomial x3+4x2+5x-2 comparing the given polynomial with ax3+bx2+cx+d
We get a=,b=,c= and d= -
Given zeros are(1,1,1)
P(1)=(1)3+4(1)2+5(1)-2=
(1,1,1)are not zeros of the given polynomial p(x).
