Question

Verify that 1,-1 and +3 are the zeroes of the cubic polynomialx x3 -3x2-x+ 3 and
check the relationship between zeroes and the coefficients.​

Answer 1

Answer:

First put given zeroes in the equation.All r zeroes of polynomial p(x)

alpha=1(a)

beeta=-1(b)

gama=3(g)

verification :

a+b+g=b/a=3

ab+bg+ga=c/a=-1

abg=d/a=-3

b coefficient of x2

a coefficient of x3

c coefficient of x

d constant term
