Question

if 1 and -5 are two of the zeroes of polynomial p ( x ) = x cube + 11 x square +23 x -35 find all the zeroes of p( x) .​

Answer 1

Answer:

Given two zero of equation 1 are 1 , & -5 if α,β,γ are zero of equation 1. the

now α,β,γ=−11,

α=−11−(β+γ)=−11−(1−5)

α=−11+4

[α=−7]

Hence its third zero is -7.

Answer 2

Answer:

Given two zero of equation 1 are 1 , & -5 if α,β,γ are zero of equation 1.

now,

α,β,γ=−11,

α=−11−(β+γ)=−11−(1−5)

α=−11+4

[α=−7]

Hence its third zero is -7.
