Question

find the cuble polynomal whose three zeroes
3 -1, -1/3​

Answer 1

Answer:

cubic polynomial,

3x³-5x²-11x-6 = 0

Step-by-step explanation:

a = 3 b = -1 c = -1/3 x²-(a+b)x+ab = 0

x²-(3-1)x+(-3) = 0

x²-2x-3 = 0

cubic polynomial,

(x²-2x-3)(x+1/3) = 0

x³+x²/3-2x²-2x/3-3x-1 = 0

3x³+x²-6x²-2x-9x-3 =3

3x³-5x²-11x-6 = 0
