Question

find the zeros of the quadratic polynomial 5x^2+8x-4 and verify the relationship between the zeros and the coefficient of the polynomial ​

Answer 1

sum of zeros= -b/a

put the value= 8/10

v = 4/5= - coefficient of x square / coefficient of x

product of zeros = c/a

=-4/10 = 2/5

- coefficient of x / constant term.
