Question

find the zeroes of the following quadratic polynomials and verify relationship between the zeroes and the coeffiecents.
1) x square-2x-8​

Answer 1

Step-by-step explanation:

x2-2x-8

x2+2x-4x-8

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

(x-4) (x+2)

x=4, -2

sum of zeroes =-b/a

4+(-2) =-(-2)/1

2=2

product of zeroes =c/a

4×(-2) =-8/1

-8=-8
