Question

find the cubic polynomial with the sum, sum of the product of its zeroes taken two at a time and the product of zeroes as 1, -4 ,8 respectively​

Answer 1

Answer:

x³-x²-4x-8

Step-by-step explanation:

alpha + beta + gama = -b/a = 1

alpha*beta + beta*gama + alpha*gama = c/a = -4

alpha*beta*gama = -d/a = 8

Let a be 1

Then b = -1 ;c= -4; d= -8

So, by ax³+bx²+cx+d = 0

it's x³-x²-4x-8
