Question

Find the Zeros of the Quadratic polynomial r^2 - 2x -8 and verify the relationship between the zeros and its coefficients.​

Answer 1

Answer:

zeroes are -2 and 4

Explanation:

x^2-2x-8

x^2-4x+2x-8

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

(x+2) (x-4)

x+2=0

x=-2

x-4=0

x=4

sum of zeroes=-(coefficient of x)/coefficient of x^2

4-2=2/1

product of zeroes =constant /coefficient of x^2

4×-2=-8/1

this is the relationship between the zeros and coefficient

this is the answer
