Question

Verify the relation b/w zoab and coefficient of polynomial 9×2-3×-2

Answer 1

9x^2-3x-2

9x^2-6x+3x-2

3x(3x-2)+1(3x-2)

3x+1=0. 3x-2=0

x=-1/3 x=2/3

-1/3,2/3 are the zeroes of the polynomial 9x^2-3x-2

Relationship between zeroes and coefficients

Sum of zeroes=-(coefficient of x)/coefficient of x^2=-(-3)/9=3/9=1/3

Product of zeroes=constant term/coefficient of x^2=-2/9
