Question

find all zeros of polynomial x power 4 + 7x cube + 5x square minus 31 x minus 30 if two of its zeros are +2 and minus 5​

Answer 1

Answer:

gamma =-4

Step-by-step explanation:

p(x)=x4+7x3+5x2-31x+30

let one a=2 (a=alpha)

b=-5(b=beta)

y=?y=gamma

A.T.Q

a+b+c=-b/a

2+(-5)+y=-7/1

2-5+y=-7

-3+y=-7

y=-7+3

y=-4
