Form a cubic polynomial whose zeros are 3,1 and 2.

Open in App
Solution

The given zeros are 3,1 and 2
So, the factors of the polynomial are (x(3)),(x(1)) and (x2)

Then the polynomial
P(x)=(x(3))(x(1))(x2)
=(x+3)(x+1)(x2)
=(x2+4x+3)(x2)
=x32x2+4x28x+3x6
=x3+2x25x6

Hence, the polynomial is x3+2x25x6
