Question

given that root 3 is a zero of polynomial x3+x2-3x-3, find its other two zeroes

Answer 1

Hello friend......
Here is your answer.......

Let it's zeroes be x,y,z.

x+y+z = -coefficient of x²/ coefficient of x³.
x+y+root 3 = 1.
x+y=1-root 3.

xyz = -constant term/coefficient of x³.
xyz=3.
