Question

find all the zeros of the polynomial 2 x power 3 + x square - 6 x minus 3 if two of its zeros are root 3 and minus root 3​

Answer 1

Step-by-step explanation:

let the zeroes of the polynomial 2x³+x²-6x-3 are

alpha, beta & gama .

then , alpha + beta + gama = -1/2

√3 - √3 + gama = -1/2

gama = -1/2

So , all the zeroes of above polynomial are √3 , -√3 & -1/2 .
