Question

show that 2 and -1/3 are the zeros of the polynomial x2-x-5x-2​

Answer 1

Step-by-step explanation:

Inorder to show the given values are zeros of given polynomial, put the value one by one

if the total value comes out to be zero, then it is zero /solution of polynomial

(2)²-5(2)-2

4-10-2

-8 not equal to zero

its not the zero of given polynomial

(-1/3)²+1/3+5/3-2

1/9+1/3+5/3-2

1/9+2-2

1/9 not equal to zero

Hence given numbers are not the roots of above polynomial
