- Find the zeroes of the following quadratic polynomials and verify the relationship betweenthe zeroes and the coefficients.(1) x^ -2x-8​

Answer»

ZEROES ARE -2 AND 4

X^2-2x-8          (on factorisation)

x^2-4x+2x-8

x(x-4) +2(x-4)

(x+2)( x-4)

x=-2 and x=4

so the zeroes are-2 and 4

sum of zeroes:- -2+4 =2               PRODUCT of zeroes=-2*4= -8

-b/a =2                                            c/a= -8

HENCE proved...!!
