Question

find the zeros of the polynomial 2xsquare -x -1 and verify the relationship between the zeroes and the coefficients ​

Answer 1

Answer:

Step-by-step explanation:

2x²-x-1 =0

2x²-2x+x-1=0

(2x²-2x)+(x-1)=0

2x(x-1)+1(x-1)=0

(2x+1)(x-1)=0

2x+1=0;x-1=0

X=-1/2; X= 1

Coefficient of sum of zeroes=1/2

Coffecient of product of zeroes =-1/2
