Question

If x+y+z=0, then find x3+y3+8........................I WILL MARK AS BRAINLIEST

Answer 1

Answer:

P(x)=3x^3-5x^2-11x-3

it is a cubic polynomial. it has three zeroes. two of its zeroes are given.

finding the factors by solving for each zero

x=-1

x+1=0

x=3

x-3=0

multiply the factors

(x+1)(x-3)

g(x) = x^2-2x-3 is a factor

now by long division method

divide p(x) by g(x)

division is shown in the attachment

when u divide u will get quotient as

3x+1

∴3x+1=0

x=-1/3

∴the zeroes are -1<3,-1/3
